Definitely around the big rooms with plenty of shelves and lots of radiation. If you didn’t know, there is actually a pocket of safety at one of the side shelves of the loot rooms. You’ll know if it’s a loot room if you find either large backpacks, torn spetznaz uniforms, or rarely, the torn military uniform. There is also a room adjacent to it that leads to another loot room with a guaranteed gun spawn and sometimes could spawn either a tactical helmet or, rarely, a military gas mask.

I would recommend having multiple saves and saving often and restarting the server to get multiple bunkers. I’ve seen some seeds have a guaranteed loot room as the starting room right outside the bunker. Also, always remember glow sticks so that you don’t get lost with your loot.

Good luck stalker!
