I found an amazing bug in Rage that inspired me to create a brand new thread. In Subway Town, as I went down the elevator to the Resistance Hideout, I, for some reason, decided to crouch as I stepped off of the elevator. I fell through the floor and landed on an invisible floor underneath the Subway Town map. I was able to move around like normal and could look up at the map above me. The map covered the entire Subway Town, the hideout and the town itself. It kind of reminded me of those top-down maps on old FPS games like Doom and Duke Nukem but in full 3D...kinda. It was really weird. It was as if I was in the testing mode for the game's developers. It also lead to that infamous 60 FPS dropping as I looked at the entire map all at once.
So, what was the weirdest bug you ran in to while playing Rage?
