This is the map of the game's and thus the bunker's structure. Do you think I'm missing anything. I wasn't planning on having the game start in the airlock but rather the entrance. And the position of the Armory will be explained through the story. But are there any types of rooms you think I should include? As I wrote this I thought about water, waste and electricity. So maybe a utilities room.
Hard to say what else you could add without knowing more about the story, but I'm always a fan of a secret/mystery room that's either hidden or off limits for reasons that later come to light. Or maybe there's some sort of sub-level all-purpose room that's been barred off because of some hazard. Like I said, I'd guess it depends on the direction the story is going.
