SVDM-2

On top of a crate near the campfire in a ruined building.

Inside the small building. To get inside, climb the crates behind it, then throw a grenade through the window to destroy the boxes blocking the door.

At the end of a walkway inside a huge cave, accessed through a tunnel overlooking the lake to the north-east. Once inside, squeeze through the tunnels; when you enter a large area, climb the pipes above a pool of acid and follow the fenced-off walkway around the corner.

At the top of the watchtower. Watch out for a grenade trap when you’re near the top.

Inside a wooden box outside the building entrance.

At the top of the watchtower.

Found next to a corpse in an underground cage.

Dropped by Leshy.
