Agents of Mayhem is an open world action-adventure video game developed by Volition and published by Deep Silver. The game takes place in a futuristic version of Seoul, South Korea, features 12 different agents from all over the world and the players can choose any 3 of them to complete different missions and/or explore the city. Each agent has their own abilities, play style and different weapons to face thousands of enemies throughout the game.

The trophy list is not really difficult but is a huge grind as you need to upgrade all the agents to Level 20, and complete 15 online contracts. There are only 3 contracts every day and you can join a group of 6 friends/randoms to help you to complete the grindy tasks required to complete them. You will also need to find 350 shards without any good in-game tracker.

Note that the online contracts trophy might require more than 15 contracts. The trophy for completing every main mission on a difficulty of 7 or higher is no longer missable/glitched with the latest patch as it's obtainable with mission select once you complete the game. The game seems to change your difficulty when you die too much on a mission so it's best to start with a difficulty of 7 and never change it until you complete the main missions.

Step 0: Contracts and Global Conflict
You should keep an eye at these trophies and start them as soon as you can because they take quite some time and require to finish missions/kill enemies so you should do this while you're playing the story. First thing, you need to complete 15 online contracts and there are only 3 contracts every day so this will take at least 5 days to get the trophy. The tasks are grindy and you only have 24 hours to complete them, you will likely not be able to complete them alone but you can join a group of 6 friends/random people and all their progress will be counted toward the task. There is no coop mode, you just join them in the contract but you can't play with them. Note that this trophy may require you to complete more than 15 contracts, please see the guide for more info.

You will also need to complete 30 agent/mayhem contracts. These ones are offline and can be completed whenever you want. To get contracts you need to send your different agents in the Global Conflict mode and when they complete a mission you will sometimes obtain contracts (1 or 3 if you buy the upgrade, which you should do ASAP). To send your agents in missions, you need Intel. You can get Intel by completing missions and killing enemies, you need to collect them after you kill them.

During this step, you will unlock:

Spreading MAYHEM

Step 1: Complete every operations on Level 7 or higher
You need to complete every mission on Level 7 or higher, there are 16 levels of difficulty (11 to 15 are locked until you have an agent at Level 20). You can choose the difficulty when you leave the Ark and choose your team, always pick 7 or higher. You can choose whatever agent you prefer but try to stick with the same agents as your first choice so you can upgrade him/her faster and the missions will be easier. The first missions can be difficult as your agents will be low level but once you upgrade them it's really easy. There are 57 missions, the first Agent missions will be locked at Level 1 but you still need to choose difficulty 7 or higher when leaving the Ark.

Some players have reported that they don't have the trophy after completing every mission at Level 7, we are not sure what is the problem but it seems that the game can lower the difficulty without warning you when you die too much on a mission. So if you start at Level 7 and die too much, the game might put you at Level 6 for the end of the mission and when you're back at the Ark the difficulty is back at 7 and you didn't notice anything. You might want to choose difficulty 8 or keep an eye on your current difficulty if you die 3-4 times on the same mission (you can see it when pressing the touchpad). This trophy is no longer missable/glitched with the latest patch as it's now obtainable via mission select once you've completed the game.

Step 2: Upgrade every agent to Level 20
After completing the game you will probably have 1-3 agents at Level 20 depending if you always took the same agents or not. Once one of them is level 20 you can upgrade him/her at level 40 if you have 20 shards. Now to upgrade the other agents, you should choose the difficulty 15 and either take your best agent to carry the other 2 or buy a lot of Seoul defences and spam them at your enemies. You can replay missions and/or lairs but the fastest option to get XP is to go clear the Outposts, Dark Matter fracking stations, Golems, etc whenever you see them on your map. If you have cleared them all, replay a mission or go inside a lair and they will reappear. This can be very difficult at difficulty 15 but you can buy Seoul defences after completing the game and spam them at your enemies to kill them all and get a lot of XP. (Don't forget to keep money to buy all the Agency upgrades).

Step 3: Collect all shards
There are 350 shards to collect in Seoul, none of them are missable but some of them are unobtainable with certain agents. You need to put an agent that can climb walls in your squad and another one that can dash (Scheherazade and Kingpin are perfect for that). The 1.03 patch make the shards appear on the map when you are close to them, but this doesn't seem to help much with the ones at the top of buildings. It's probably best to follow some videos or you might have to scour the city for hours to find the last one. Try to open chests when you see them as they can give you blueprints to unlock new vehicles.

During this step, you will unlock:

X Marks the Spot

Shard Shark

Step 4: Clean up
You will probably have all the trophies by now and will only need to farm online contracts to finally get your platinum. If you're still missing any trophy, please refer to the guide to see what you have to do to unlock them.

Contract Thriller

Complete 15 Connected Contracts.
(9)
UNOBTAINABLE DUE TO SERVER CLOSURE

You need to complete 15 online contracts, there are only 3 contracts every day so this will take at least 5 days to get the trophy.

The tasks are grindy and you only have 24 hours to complete them, you will likely not be able to complete them alone but you can join a group of 6 friends/random people and all their progress will be counted toward the task. You will be required to kill a certain amount/type of enemies, open chests, complete lairs in the global conflict etc. but the enemies in the VR room do not count for the contracts.

When a contract is completed and if you're online, you will have a notification on your screen. If it's completed while you're offline, you will not receive any notification when you're back in the game but the contract will be gone in your missions menu, it means it's been completed and it should count. However, if a message saying "the expired contracts have been deleted from your list" appear, it means the timer was over and the contract wasn't completed.

You can't track how many online contracts you've done, you can only see how many contracts (both offline and online) you've completed in the Mayhem Database in the Ark.

There is no coop mode, you just join them in the contract but you can't play with them.

Note that this trophy may require to complete more than 15 contracts, some players have reported getting the trophy after 18, 20 or more contracts completed, so keep playing until you get the trophy. We don't know yet if you have to create the contracts or if joining them is fine, if you have to be online or not, if you need to actually work on the contract or if you can be carried by the other people... Some players have got the trophy while joining other contracts and were not online when the contracts were completed so it shouldn't matter.

Here are some tips if you're looking for a certain type of enemies:

Elite enemies: These are the enemies with "commander" in their name. They spam randomly while in Seoul and they are pretty rare, especially the Elite Swarmtroopers. The best solution would be to replay missions/lairs and when you see one, kill him and restart the checkpoint to farm the kills.
Gremlin Tech: Buy a lot of Seoul Defenses and simply spam them.
Special Kills: Take Oni and play on difficulty 0, you will one shot almost every enemy and his special ability instantly reloads with one shots.
Tanktroopers/Bufftroopers, etc: They can spawn in the city when your Alert level is at 4 or 5, or inside lairs when you have to kill a Leader, kill them and the leader and restart the checkpoint.
Golems, Ice Barrage, Fracking: If they don't appear on the map, take over Outposts and Relic's trading companies and they should appear.
Legion Alerts/Pride Captains: You will need to kill a Pride Captain to clear the Alert level, kill civilians/explode vehicles in Seoul until your first bar of Alert level is filled up, then kill Legion until the captain appear. Rince and repeat, you just need to wait about a minute between 2 alerts.
Turrets: Replay Operation: Tecnologia, there is a Turret near the beginning of the lair, destroy it and restart the checkpoint to farm it.
Boom bots: Replay Operation: Star Power: All the Rave until you reach the garage and interact with 2 cars. There will be 8-9 Boom bots, kill them and restart the checkpoint.
Contract Killer

When sending your agents in the different regions of the Global Conflict, you will sometimes obtain contracts. You can buy the Frugal Calendar App in the Requisitions area to get 3 contracts instead of 1.
You can see your available contracts in your mission menu under Contracts. The daily connected contracts don't count toward this trophy. Some contracts are easier than other, some of them need to be done with a certain agent while others can be done with anyone. Don't worry too much about the hard/grindy contracts and try to complete the easy ones while you're normally playing. You will get many easy contracts if you always send your agents when you can, and will be able to do them without worrying too much about it.
X Marks the Spot

Find and open a large loot chest.
You will see many chests around Seoul or in lairs but the ones you need for this trophy are the large gold chests. They are random and unlimited so keep using your scan to find them while you're going after shards.

One car, the Mongoose, is automatically awarded in story mode and cannot be unlocked with blueprints.
Hardcore Gamer

Complete all Operations on Difficulty Level 7+.
(8)
This trophy is no longer missable/glitched with the latest patch as it's now obtainable via mission select once you've completed the game.

There are 57 operations to complete and you need to complete them all on Level 7 or higher, there are 16 levels of difficulty (11 to 15 are locked until you have an agent at Level 20).

You can choose the difficulty when you leave the Ark and choose your team, ALWAYS pick 7 or higher. Don't ever set the difficulty to a lower level to be sure.

The first missions can be difficult as your agents will be low level but once you upgrade them it's really easy. The first Agent missions will be locked at Level 1 but you still need to choose difficulty 7 or higher when leaving the Ark.

Some players have reported that they don't have the trophy after completing every missions at Level 7, we are not sure what is the problem but it seems that the game can lower the difficulty without warning you when you die too much on a mission. So if you start at Level 7 and die too much, the game might put you at Level 6 for the end of the mission and when you're back at the Ark the difficulty is back at 7 and you didn't notice anything.

You might want to choose difficulty 8 or keep an eye on your current difficulty if you die 3-4 times on the same mission (you can see it when pressing the touchpad and go to Squad).
Globally Offensive

Complete the Moscow Global Offensive.
After reaching a certain point in the story, you will unlock the Global Conflict. You will be able to send an agent to different parts of the world and you will need to wait a certain amount of time until the mission is complete. You can still play while your agent does this mission but you can't take said agent in your squad. (You can also buy an upgrade at the Ark to send 3 agents at the same time) To be able to send your agents, you will need to collect Intel. Intel can be collected when killing the enemies, they are green glowing icons so try to collect them when you kill your enemies especially the big enemies as they give more Intel.

These missions can't be failed, you just need to wait a certain amount of time and the mission will be completed. You will obtain contracts or resources most of the time, but sometimes you will see a red icon which means you have to complete a lair to continue the global offensive. Once you've completed a region, you will receive a key to unlock another region. Once you've completed all regions, you will be able to complete the Moscow Global Offensive, which is a lair with strong enemies and the minimum difficulty is set to 10. It's highly recommend to have a good squad of fully upgraded agents to attempt this. Once you've completed the lair, you will get the trophy and will be able to send your agents again, and complete all the regions over and over to get more contracts, etc.
Super Agent

Reach level 40 on any Agent.
Once you reach level 20 with one of your agent, you will be able to upgrade him/her to level 40 if you have 20 upgrade cores. Open your menu, go in Squad, choose an agent, go in Upgrades, Super Agent Level and purchase them until you reach Super Agent level 20 which is also Level 40.
Get Personal

Complete all agent personal missions and get all agents to level 20.
(1)
You only need to upgrade 12 agents, if you have Gat or any other DLC characters you can upgrade them to Level 20 instead of another agent. (Thanks to TheManUtdFan for the info)

The personal missions for all the agents are available right after unlocking the agents, you can see the agents levels at the armory in the Ark or in the Squad menu.

After completing the game you will probably have 1-3 agents at Level 20 depending if you always took the same agents or not.

To upgrade the other agents, you should choose the difficulty 15 and either take your best agent to carry the other 2 or buy a lot of Seoul defences and spam them at your enemies. The Seoul Defense is unlocked after completing one of the last missions.

You can replay missions and/or lairs but the fastest option to get XP is to go clear the Outposts, Dark Matter fracking stations, Golems, etc whenever you see them on your map. You can also make a mess in the city, kill civilians, explode vehicles to increase your Alert level, and kill the enemies when they're coming.

This can be very difficult in difficulty 15 but you can buy Seoul defences after completing the game and spam them at your enemies to kill them all and get a lot of XP.

You can easily find secret rooms in lairs, after killing all the enemies in a zone, try to open every door that you can see before going in the next room. When one of them is open, try to find a panel to hack/activate that will open a new area. Secret rooms almost always have chests so if you have the upgrade to see them with your scan, you can see if there is a potential secret room inside the secret room or no. Not every secret room have secret rooms so it's really luck based.

Get 15 "All Perfect" hacks.
(1)
There are a lot of things that you can/need to hack in Seoul and inside lairs. When hacking, you need to press when the cursor is in the orange or yellow zone. To get a perfect hack you need to press when it's in the middle of the yellow zone, but you will need to do that for all the nodes for it to count, not just one.

If a hack has 3 nodes and you get only 2 perfect hacks, it won't count. If you perfectly hack the 3 nodes, it will count as 1 perfect hack. Do this 15 times to get the trophy.
