Alien 3 canteen. There is religious symbols and doodling from the inmates in the background. I had never noticed it before, its a nice touch.
The skeleton thing seems to be a bit odd when you think about it. It would take longer than two weeks to be decomposed to that extent. While you could say that maybe the chestbursters/aliens had eaten them, it woud not explain why other corpses are then left untouched.
