Welcome to Chicago and welcome to one of the best games to have come out on the PS4. This guide is designed to assist you in getting the platinum trophy with as little resistance as possible. The game is designed to be both a single player and a multiplayer experience at the same time.
You can turn off online invasions from the options menu, but if you’re trying for platinum, you want to keep this on. There is a trophy for being tailed 5 times and you want to try to get those while your playing and you never know when you’re being tailed. Yes, it will open you up to getting hacked from time to time, but most players will tell you that it’s not as frequent as you’d think it was. If you do not engage in multiplayer yourself, you won’t get hacked that often.
Step 1 – Play through the story – Simply play through each of the 39 main stories and enjoy the game. You will automatically start the game on Normal difficulty, but if you choose to, you can change the difficulty at any time under gameplay in the options menu. You can choose to do as much or as little of the side missions, collectibles, mini games, etc. Many side missions aren’t available until you discover their locations through hacking of citizens. So profile and hack as many as you can to unlock them even if you plan on doing them later because this will save you time later.
The two other things I would highly recommend you do throughout all your time playing the story is to check in at any hotspot locations you run past as part of the Geolocated trophy and work on finding songs for Disc Space Full by profiling citizens or using the SongSneak app. See each of their trophies descriptions for more info.
You can, and probably will, earn some the Miscellaneous trophies as outlined in step 4.
Note– There are some side missions and collectibles that you can not earn until you have progressed far enough in the main story.
Step 2 – Complete Side Missions, Investigations and Collectibles – If you open up your smartphones () and check out your progression you will see all the available activities as well as your progress towards them. You will earn these trophies under each of the following categories
- Road Rage
- End of Line
- Basest Base
- Revoking Client Privileges
- Sanity Check
- Darkness Looms
- Saturday Night Special
- Disk Space Full
- Clear Signals
- System Mangler
- Audio logs not needed for trophies
- Piggyback (Also Stealth Cookie if you remain undetected for one)
- Online Decryption not needed for trophies
- Social Lubricant
You’ll also need to play these specific games for the Power Cycle trophy.
- Drinking Game
- Shell Game
- Slot Machine
You can go about these in any order you wish but the first thing you want to do is unlock all the ctOS towers. These will appear as large red icons on the map. See Clear Signals for their locations and how to unlock each. For each tower that you unlock, you will reveal nearby investigations, collectibles and other points of interests.
IMPORTANT – Some side missions or collectibles won’t appear on the map or available at all until you have progressed far enough into the main story.
Step 3 – Online Contracts – This step will require you to participate in the online. You can select online contracts by hitting and selecting online contracts or by going to the map and hitting or to tab over to the online map. From there, just select which event you want to participate in. You do not need to do any Online Decryption, Free Roam or Mobile Challenges. Just do the following:
- Complete 10 Online Tailing
- Do 1 tailing without being seen
- Complete 10 Public Online Races (just finish, no need to win)
- Succesfully complete 10 Online Hackings
The only other online trophy left is the hidden trophy called Traced. This requires other player to be placed in your game and follow you. See that trophy for more information.
During this step you will earn:
- Stealth Cookie
Step 4 – Miscellaneous Stuff – At this point, you should have most of the trophies, and probably several of these as well through natural gameplay. In case you didn’t, feel free to get these done at this time.
White Rabbit Object
Black Hat Trick
This is the platinum trophy and is unlocked automatically when all the trophies have been unlocked.
Take down Maurice
Story related, can’t be missed. This is earned at the beginning of the first mission.
End of Line
Complete 40 Fixer Contracts
These missions will open up to you as you profile citizens and then hack the ones that offer Fixer Contracts. You can drive to the locations on the map with the icon above or you can open your smartphone and select a Fixer Contract from there and be given a waypoint to the location. Fixer Contracts all offer a cash reward upon completion.
There are four types of Fixer Contracts, each with their own method for completion. Complete 40 of the 46 contracts to get the trophy.
Decoy – This requires you to be a decoy and race through specific monitoring points to attract police attention. You just have to reach those points and not get caught.
Getaway – You have to steal a certain vehicle and deliver it to the drop zone undetected –
Interception – Seek out and hack a targeted driver and take him out
Transporter – You need to take a vehicle to drop off points while taking as little damage to the vehicle as possible.
Complete every Gang Hideout
Gang Hideouts will become available as you progress through the story and profile and hack citizens with information about them. You can’t access these through the smartphone so you’ll have to identify the icon listed above on the map and proceed to each of these points. There are 15 total. Each of these will offer a skill point as a reward.
The missions are all the same for gang hideout jobs.Find and Intimidate a target by performing a non-lethal takedown. You can stealth your way through it to get to your target or you can fight, but no matter what, you can’t kill the target. You have to knock him down with
They Call Him The Vigilante
Complete every Investigation
There are five different Investigations, each of which are there own trophy. Each of these investigations require you to collect certain objects and then complete a bonus mission at the end. See the following trophies for more information on each:
- Revoking Client Privileges
- Sanity Check
- Darkness Looms
- Saturday Night Special
Completing each of those trophies will earn you this one.
Complete every Privacy Invasion
There are 30 privacy invasion collectibles. You can find them on the map indicated by the eye icon shown above. These will not appear on your map until you unlock the nearby ctOS towers. See Clear Signals for information about how to unlock those.
As for completing them, you have to do one of two things. Either hack the security router which will put you in the little hacking mini game where you need to turn the wires the correct way to gain you access or you’ll need to unlock nearby ctOS boxes to which is just simply finding the nearby panels to unlock that will give you access to the intrusion panel. It’ll be one of those two methods.
Once you have found your way in, you’ll be peeping in on the events in a room. You do not need to do anything further and can immediately exit out. You will earn XP for each completing invasion
Complete every Criminal Convoy
To gain access to Criminal Convoy missions, you will need to profile and hack citizens. There are 18 total and you simply need to kill or knock down your targets. The convoy will start at one point and will be en route to another point. I found that getting a heavy duty vehicle and using that to stop, and then run over the criminals when they get out of their vehicles to be a quick and easy way to complete the job.
You can take out everyone in the convoy, or just the intended target and then escape by vehicle.
Use the Crime Detection System to take down 20 confirmed criminals
These will pop up quite frequently. You can either profile and hack citizens with information about crimes or you’ll get a notification as you’re traveling around the city and can place a waypoint immediately to go to the location. These will look like this on the map.
Each of these criminal take downs are all the same. Travel to the area with the circle and use your profiler to identify the suspect. Get noticed by the suspect and you will fail and need to find another detected crime. Stay back and wait until the ctOS alert tells you to intervene at which point you’ll need to chase him for a non-lethal takedown or shoot him. Non-lethal takedowns are best since they don’t risk someone calling the cops.
Perform 10 vehicle take downs
This is nearly unmissable. All you need to do is to damage and take out 10 enemy vehicles. Since there are many missions (main and side missions) that require you to take out remaining enemies or escape, just use this time to ram the other vehicles until they are destroyed.
You should get this naturally while playing through the main game.
Using non-lethal takedown, stop 10 civilians from calling to report you
This is pretty simple. At many times throughout the game, you will commit crimes. And if a citizen witnesses you committing a crime they will call the police. You will hear their conversation reporting you to the police and you’ll see a red warning triangle above there heads.
Before they finish the call with the police, you need to stop them. You can do this by running up to them and hitting to end their call, or use a Jam Coms from a distance.
I found the easiest way is just to use the Jam Coms. Make sure you have acquired this skill first and then you can craft them as long as you have the supplies. This is the most useful item to avoid being chased all the time by the cops. Whenever you car jack a vehicle, if you notice the driver starting to call the police, just hit when the Jam Coms is equipped to stop the call. Do this 10 times for the trophy.
Tag 100 enemies
This should be earned easily during your main story run. All you need to do is profile 100 enemies by hitting and looking at them.
Participate in 5 different City Games
There are many games that you can participate in. If you play each of the 5 games below, you will get the trophy.
Slot machines are not listed under games if you look at the progression wheel, but it is required for this trophy. You can find a slot machine in the bar inside the baseball stadium. Just look for the icon on your map.
For this trophy, you do not have to win the game. You only need to play it, win or lose. To save time when playing poker, you can go all in every hand until you lose. The only ones that you’ll need to play until completion is Chess and the Drinking Game and that’s because they are needed for other trophies. See Freeware and Social Lubricant for info on those.
Kill 4 enemies within a single instance of Focus
Focus is a skill you need to unlock from the combat skill tree. This allows you to slow down time. There are also upgrades to this which will allow you increase it’s duration and to slow time further.
To start and stop focus, you hit . while under the effects of a single Focus you will need to kill 4 enemies. You will need to have 4 enemies relatively close together to pull this off. Two methods that will prove effective if you don’t get this during the story.
Get the cops after you and when at least two cop cars arrive to your location, use focus and shoot them. You can shoot them through the windows.
The other way, in similar fashion, is to place down IED’s in a location where you know two or more cop cars will pull up to. When the police arrive, activate focus and immediately set off the bomb. You’ll see this method in the video below as I lure the cops just outside Navy Pier in the Mad Mile. This will also unlock Black Hat Trick as well.
Escape 15 police chases
To initiate a police chase, you will need to commit a crime. If you look under the mini map you will see 5 squares. Each one represents your wanted level. The wanted level is represented in three colors.
- White – You’re safe
- Yellow – Police are using the ctOS to scanning for you
- Red – Police are after you
The easiest way to escape a police chase is to have the police after you with the lowest possible wanted level. Once they are after you, you will need to escape them. To farm this, just jack cars until someone calls the police. They will initiate a scan and then you will have just a level one police chase. This will not include helicopters and escaping is simple.
You can either use a fast car to drive as far away as police or use your hacking to trigger traps to take out any pursing squad cars. If you have it, the steam pipe hacking upgrade works well. You will then need to exit the search radius which is the large white circle on your mini map and once you do, you’ll be clear.
Escape a level 5 police chase
The level 5 police chases are not for the faint of heart. You will have helicopters tracking you from above and they will be sniping at you. You’ll also have armored policeman and a relentless number of squad cars coming after you.
You will need to build up to level 5 first. The best way to do this is by getting a level 4 wanted level before the police start coming after you. A good place to do this is around Navy Pier. There are many civilians walking around (especially during the day time). Start shooting as many of them as you can and try to take out any that are calling the police. Your wanted level will rise quickly before the cops are even after you.
If you do this outside Navy Pier, you can enter the coffee shop nearby and pick off police with your guns and toss grenades or IED’s outside the window to build up your wanted level to level 5. They won’t enter the shop. You will need to make your escape after you get to level 5. You have two options. If you have a fast car nearby, you can try to outrun them. The method I found very easy if you did this in the coffee shop is to exit the back door. All the cops are out front and if you exit the back door and run left to the lake, there will be a boat waiting for you. Hop in that and the only thing that can track you is the helicopter. You can take care of that by using Jam Coms or shooting the pilot or sniper. Once you have control of the boat, just drive out to sea. To see this plan executed, watch the following video
White Rabbit Object
Escape 15 police scans
Police scans are initiated when a citizen witnesses a crime and calls the police. Before they send the cops after you they will scan the area to locate you. You will see yellow circles on your mini map and all you need to do is exit the circle. Yellow circles will keep popping up and you’ll need to keep moving. Next to your wanted level is a percent and if that reaches 100%, the cops will be on you. If you stay out of the circle, it will drop to 0% and if you stay out of their scans for a few moments longer, you will have successfully escaped the scan.
There is one item that will help you out greatly. That is the Jam Coms. You can craft these at will if you have the materials and have purchased that from the crafting skill tree. Make sure to have it selected by holding and selecting it from the weapon wheel. To use it, hit If you use it while in range of the police scanner, it will temporarily turn the circles white and give you a few precious moments to get out of range. You may need to use more than one to escape the scan.
Escape a level 5 police scan
See White Rabbit Object for basic information about police scans. For this trophy, you will need to build up a level 5 police scan. This is probably more tricky than evading a level 5 police chase. You need to build up your wanted level to level 5 before the police scan even starts. This means that you need to prevent anyone from successfully calling the cops.
The easiest way to do this is to go to a well populated open area with a bunch of civilians with the maximum number of Jam Coms with enough materials to craft more. I use the area outside Navy Pier in the Mad Mile for this as there is a large open area and tons of people. Start killing as many as you can and very quickly. Try to locate and target large groups of people. Pay attention to anyone who is calling the police and take them out quickly.
If someone manages to call the police before you reach level 5, you can still take out people during the scan process. You have two options once you reach level 5. Either jump into a very fast car and drive away or hop into a boat. Either method works well, one has less traffic. In either case, you’ll need to make good use of your Jam Coms to disable the scanners. Keep using them until you get far enough away and craft more while on the run if you need to. Here’s a video of me shooting up at Navy Pier and then jumping into a nearby boat.
Shoot out a tire on 15 different vehicles
This is really easy. Just find 15 cars and shoot out one of the tires. It can be a parked car or an enemy vehicle. It doesn’t matter. Just make sure you shoot out the tires to 15 different vehicles.
Black Hat Trick
Kill 3 enemies with a single IED
This is a pretty simple trophy. Either find, or craft an IED (requires you to purchase the skill to craft) and blow up 3 enemies with a single IED. You can use this on any enemy including police who are chasing you.
There is also a mission during the story called Uninvited during the main story in Act 2 where you need to defend an area. On each end of the area will be a car with four people each. You have about a minute of setup time so just place an IED in each of these locations and when the cars arrive, blow up the bomb.
If you don’t get it during the main story, you can get this easily against cops. Cops tend to arrive in bunches and park their cars near one another. Tossing out and blowing up an IED near the police car will easily get you this trophy. You can view the video in Magic Smoke to see this against the cops.
Revoking Client Privileges
Complete the final mission in the Human Traffic Investigation
These are a set of side missions where you need to find suspicious buyers and then invade their apartments and scan their briefcase. You will need to go to the icon shown as on the map and use your profiling to find the buyer. Once you have identified the buyer, you will will need to go to their apartment which will be indicated as on the map. You can immediately add the waypoint once you find the buyer. Now all you need to do is go to the apartment and scan the briefcase. You will need to find and locate 10 of these events in the city. Once you have found all 10, you will be given a new 11th bonus mission that will require you to hack someone and eliminate him. All the locations and the final mission walkthrough can be found in the following video.
Saturday Night Special
Complete the final mission in the Weapons Trade Investigation
There are 9 weapon crates that you need to locate. These crates are all shown on the map with . Each of these locations will require you to find a panel to unlock in order to open the garage door where the weapon crate is located. You will need to scan each of the crates. Once you have found and scanned all of them, you will get a final mission. This won’t be available until after you meet Tobias in the main story.
The final mission requires you to survive 3 waves of enemies. The final wave will include many armored enemies and enforcers. I highly recommend bringing IED’s, grenades or any explosive weapons for that final wave. It will also help if you have the Enforcer Combat Take Down skill so you can sneak up behind the enforcers and stealth melee them, but that’s optional. For all the locations as well as a walkthrough of the final mission, watch the following video.
Collect all 8 Burner Phones
All the burner phones are Maurices Audio Logs. The first one is given to you as part of the first mission but the other 7 can be located on the map with this icon . Not all of them will appear on your map right away so keep playing until they do. For a location of each of them, watch the video.
Complete the final mission in the QR Code Investigation
QR codes are digital codes that can be read by smart phones, or in the case of this game, security cameras. You want to head to the area marked with on the map. There are 16 total and then you will need to complete a full 17th mission Once in the area, you will need to find the pieces of the QR code. The codes are not whole and you will need to find the different fragmented pieces of the code and then find the security camera that is the proper distance and height away from the codes so that the pieces will all line up when looking through the camera.
As a side note, the QR codes are real and provide some humor if you’re inclined to scan them with your own QR reader. Once you have found all of the codes, you will be given a final mission where you need to hack your way into an apartment. In the following video, I provide you the puzzle solutions to each of the codes as well as the final mission walkthrough.
Complete the final mission of the Missing Persons Investigation
Travel to each of the missing persons locations which is shown with this icon on the map . There are 6 total and then a final 7th mission once you found all the missing people. At each location, you need to scan a body. Once you have completed that you will need to travel to Pawnee for the final mission which will just simply require you to do the same thing in the Enforcer trophy and just wait for the crime to be committed and then intervene. Here’s a video of each location as well as a walkthrough of the final mission.
Check in at every Hotspot
There are 100 hotspots scattered throughout Chicagoland area. These are all clearly marked with a . Just travel to each of these locations and you will be prompted to press to check-in. That’s all you need to do at each of these locations.

Unlock every song with the SongSneak app
Please Visit this post for specific locations that play each of the 23 songs – SongSneak Location Guide
There are 23 songs that you need to acquire. 3 of them are story related, 3 of them must be hacked and 17 of them can be acquired with SongSneak. To acquire a song, you can profile and then hack citizens that have one, or you can acquire it through the use of the SongSneak App. Profiling citizens is easy enough, but you will need to profile hundreds of them before you find one that has a song, especially once you’ve collected most of them. The other way is to use the SongSneak app on all but the 3 songs that require hacking.
The SongSneak app works just like the Shazham app we use in real life. You open up the app whenever there is a song playing nearby and it’ll scan for the title and artist. If you do not have the song already, you will permanently acquire it. You can visit a number of places which have a song playing for you to scan.
- Gun Stores
- Clothing Stores
- Coffee Shops
- Pawn Shops
Use the SongSneak Location guide linked above to find specific buildings that play specific songs and then hack citizens until you get the 3 required for that.

Complete level 10 against all 3 Drinking Game opponents
There are a few bars that you can enter and participate in a Drinking mini game. Look for the drinking game icon on the map . This is probably the most difficult trophy in the game.
You will need to successfully complete level 10 against all 3 opponents. The first opponent will require you to complete a QTE type event. You will need to use your as a cursor and move over the button and press the matching button. Sometimes the button prompts will move, change button or even require you to hit a series of buttons while your cursor remains hovered over it. The final one will appear difficult in the video below, but the first 9 levels will sufficiently prepare you for it.
The second opponent requires you to use both analog sticks and move the cursor into the squares for a moment of time and then hit either the or buttons. Just like the first opponent, you’ll get this down.
The final opponent is the Extreme Drinking Game Challenge. This will alternate between both methods provided by the first two opponents and amp up the difficulty considerably. You will need to be much quicker. This, more than anything, will require some practice. You will fail and when you fail you wake up drunk elsewhere in the neighborhood. There’s nothing new about the QTE button game other than being more difficult, but there is a new twist on the blue and yellow analog stick game. If you see a orange circle, that means the R or L stick is reversed. So up is down, left is right, etc. Also, when both sticks are involved, sometimes it’s a mystery as to which one is which.
I’ll admit that this is a little frustrating and starts to get tedious, but stick with this and you will get it
.For the button push games
- Pay attention to the countdown timers. Some count down slower like the ones that require multiple inputs on the same one (the ones with the dots above them)
- If you hit one with a chain, it will create one or more additional QTE’s. The countdown timer on the additional ones starts right away so if you hit another chained one the ones that appeared first should be done first.
- Finding a pattern that works is much better than just randomly flying around.
- Anticipate the locations of moving ones. If they are moving in a circle, approach it from the opposite direction.
- If your circle is covering two of them, you can hit both buttons at the same time.
- For the ones that change icons every couple seconds, try to memorize which ones they switch between.
- The detection radius is a little forgiving and you don’t need to completely cover them with your circle.
For the Yellow/Blue circle games
- When you have a moving target that bounces off a wall, you don’t have to move the stick but just a hair to keep it centered. The game will automatically turn direction for you on your stick icon.
- when you have both a yellow and blue on opposite sides of the screen, focus on just the one and slowly move the other one around blindly until you get it.
- When you need both in the same circle, attempt to get both of them in the same spot and then move them together into the circles.
- if all else fails, get a second person and you each control just one Analog stick. Also flipping the controller when they come up backwards may help or changing the x and y axis in the controller setup menu.
Invade and successfully hack 10 enemy Fixers in Online Hacking
This is an online trophy and will require you to hack other players. If you hit the touchpad, or select button on PS3, and hit or , it will bring you to the online contracts menu or you can select online contracts from the phone directly by hitting .
You will need to select Online Hacking for this. This is a 1 versus 1 event where you will need to seek out the other player and hack their phone. Once you start hacking you will see a progress bar showing you how long until your hack is complete. You are unable to harm your opponent at any time.
To successfully steal the data, you have to avoid being profiled by your victim. You will need to stay well hidden, however, that’s easier said than done. On your victim’s screen, there will be a purple circle showing your approximate location. As the hack continues, the circle will become smaller until there’s a very small search area for your opponent.
There are going to be a few cases where you will jump into a game where the other player has seemingly fell asleep. This will easily get you the win. But that won’t happen all the time and you will have to remain well hidden.
A tip that works well for me is to steal a larger vehicle, like a van. Park the van near your victim and just stay hidden behind it. You will see his location through the van itself and can always circle the van and stay out of cover while he has no clue where you’re at. Watch the video below to see how easy it is
Invade and successfully observe 10 enemy Fixers in Online Tailing
From the Online Contracts App, select Online Tailing. This will put you into another players game and your only goal is to tail and observe him. The other player will not even know you are there unless you are profiled. Once in the game, just get close enough to profile him. You can use security cameras to get a closer look and the closer you are the quicker you’re in and out of there. Successfully complete one of these without being spotted and you will earn Stealth Cookie.
Complete 10 Public Online Races
This is an online race featuring 2-8 players. Select this from the Online Contracts App and then select “Join Public Session”. The only thing you need to do is finish the race by racing through checkpoints. You do not have to win the race, just complete it. After the leader has crossed the finish line, you have a limited amount of time to finish before the race so make sure you are hitting those checkpoints and get to the end.
Complete every ctOS Breach
ctOS Breaches are listed as collectibles in the progression wheel. There are 16 total and you need to complete each one. Once you reach this icon on the map , just hack it and it will unveil more boxes for you to hack. You will have a time limit to travel to each of their locations to initiate the hack.
Complete an Online Tailing without being detected
Unlock every Skill in the Skills Tree
There are 52 skills that you need to purchase to unlock everything in the Skill tree. You do not need to unlock the online Notoriety Skills for this trophy. Many of the skills cost multiple skill points that you earn for leveling up and completing various events. The total number of skill points required to purchase everything is 137.
There are a few skills that have a prerequisite other than just needing the available number of skill points. Those are
- Quick Switch- Requires you to catch one criminal through crime detection. See Enforcer for info on those
- Critical Focus – Complete 1 Criminal Convoy
- Rapid Reload – Complete 5 Gang Hideouts
- Maximized Focus – Complete 10 Chess Puzzles
- Auto Weapons Expert – Reach Wave 5 in NVZN Mini Game
- Offensive Driver – Complete 5 Fixer Contracts. See End of Line for info on those
In addition to those prerequisites, you will need to also get to level 50 and complete each of the Gang Hideouts. That will put you at a total of 137 skills.
Unlock every ctOS Tower
There are 13 ctOS towers in the game shown with the big red icon. Unlocking them will show points of interests such as collectibles and investigations. Keep in mind, not all points of interest will be exposed on the map until after certain points in the story so if you can’t find one and haven’t beaten the game, then you need to keep playing the main story.
To unlock them, you’ll need to gain entry to the base of the tower and install a backdoor. Each of these are basically a puzzle. There will always be at least one locked door that you need to find the unlock panel for.
Here’s a guide to unlocking each of the 13.
Complete Act 1
Complete Act 2
Complete Act 3
Complete Act 4
Complete Act 5
Get tailed 5 times
- In free roam go into options then online and disable “Online Invasions”.
- Go back to the game so you see the white emblem on the left side of the screen notifying you that the game is saving.
- Go back to “Online Invasions” and switch it back on.
- Go back to free roam and do nothing for about 10-20 minutes and then check your recent players met to see if anyone has joined you. If you’re good enough, you will be able to spot people coming into your game. If you spot someone suspicious, try pausing the game and if the background is moving on the pause screen, someone is in your game.
I did the above method each time someone had tailed me.
Do not have your phone out profiling anyone!
