Instructions
Collect the schematic to make your trap. These are hidden throughout the rooms and tunnels in the game. You're able to find schematics for explosive, stun and gas traps.
Find the components required to assemble the trap. Search through cabinets and lockers in every room to collect a stockpile of components.
Walk up to any workbench and select the type of trap you want to make. The trap is added to your inventory.
Cycle through all your traps with the "R1" button. Stand in the spot where you want to place the trap.
Hold down the "R2" button, and press "L2" at the same time. The trap is set. Arm or disarm it by clicking on the trap.
