Payday 2

The four pieces of the samurai armor are in the vault inside the warehouse. To open it, two keycards must be used in less than ten seconds on the readers on either side of the door. Failure to do so will lock the vault permanently. Up to four keycards spawn on the map, at the following locations. The higher the difficulty, the less keycards will spawn.

Held by the guard watching the camera. Killing this guard will also disable cameras.
Held by the only worker with a orange suit and yellow hardhat.
Held by a random patrolling Murkywater mercenary.
Appear in one of the locker rooms, the kitchen, or offices on the ground level.

Once the vault is opened, secure the pieces immediately, as mercenaries (and cameras if not previously disabled) will be alerted. You may want to wait until all other loot in the warehouse is secured before opening the vault. This can also be completed solo. Collect the keycard from the camera guard and wait for the yellow helmeted worker to enter the warehouse. Hwill regularly takes a break at the location between the trucks and the stairs. Once he is inside and away from a guard's sight, kill him, bag the corpse, and throw the body bag in the sewers. When clear, insert your keycard in the left side reader, run to where you killed the worker, collect the keycard, then run back to the vault and use it on the right side reader.

Enter your inventory and find a gun or mask to rename. Select the gun's or mask's name above its stats, then rename it.

Complete the heist in stealth mode because triggering the alarm makes it impossible to bag any corpses. Purchase the Body Bags asset in the pre-game lobby if you are playing solo. After assaulting the bank, destroying the cameras, killing the guards, answering the pagers and pacifying the civilians, bag two guards and two random civilians. Place the body bags under the Christmas tree at the front of the vault or behind the teller.
