From Before I Play
- Every stage has a tiny, floating purple pixel which will flash if you are wearing the Owl Mask. In order to unlock the secret ending of the game you will need to collect each and every one of these.
- Read the newspapers since a lot of people missed out that it takes place in an alternate time-line US.
- Prepare to die like crazy due to random variations in the AI's reactions and routines.
- When transitioning floors after killing everyone go and find the best weapon available before moving on. Each floor is a checkpoint and you'll always respawn with what you walked in with.
- Use the lock-on. Love the lock-on.
