Side Notes:

So continuing on from where Chapter 14 ended, but this time NOT using the room 502 key to get the UFO ending. This is a walkthrough to the rest of the game.

Costume is the "Sprinter" costume. Gives unlimited run, unlocked by beating the game in under 2hrs.

Tesla Rifle. Unlocked by getting the UFO ending. Comes with unlimited ammo. Possibly the best firearm in the game.

Everything maynot make much sense storywise yet, but it will hopefully make sense soon. The games "Bad" ending is quite shocking to say the least.

Stay WELL away from Butcher. If you get too close he has a one hit kill attack. Under no circumstances let him grab you. The fight is pretty awful to be honest, and its not helped by the camera.
