Inside a bag next to a corpse in the bunker, accessed via an entrance to the north. Guarded by a pair of telekinetic mutants. Works with the SEVA-D Suit.

Inside a boarded up room at the end of a boobytrapped corridor. To get inside, you’ll need to destroy the board blocking the door by shooting through the window outside, then disarm a few tripwires. Works with the SSP-100 Discovery.

Inside a backpack in the kindergarten’s boobytrapped bathroom. Works with the PSZ-9D Duty Armor.

Inside a safe in the middle of an old tire. Works with the Ballistic Helmet.

Inside a duffel bag on a broken piece of boat at the water’s edge. Works with the SEVA-V Suit.

Works with the Mask-1 Helmet. Found inside the underpass, accessed through a tunnel to the north. In the room filled with vehicles, pull a lever on the wall - you’ll then need to climb some stairs inside a room in the corner, and go through a heavy-duty door to find the blueprint inside a backpack on the table.
