Apocalyptic

You wake up. Your body aches. You look around and realize you're in some kind of capYousule. Several red lights flash, and you see the text 'critical error' illuminated in large letters. You look for a way to open the capsule and find a red lever that says 'exit'. You pull the lever with all your strength, but it's difficult to move. With a mechanical click, the front of the capsule opens. As you climb out of the capsule, you find yourself in a circular room containing other capsules, twelve in total, including yours. Various tools and weapons hang on the wall. There are also a few lockers with clothes and equipment. You have no memory of who you are, where you are, or even what you are. You see yourself in a glass capsule and look at yourself for the first time.
