Steam now offers online sales of Chainsaw Warrior, the video game adaptation of the boardgame of the same name from Games Workshop (thanks Andrew). Here's word:

Chainsaw Warrior from Games Workshop is the classic nail-biting game for one strong-nerved player! It's the year 2032 and spatial warping has opened a hole into another dimension in the midst of the old municipal buildings at the heart of Manhattan. Bizarre and dangerous creatures are flooding into our dimension, intent on destruction. Behind their actions is a controlling intelligence known as 'Darkness', who intends to drag New York back into the warp – destroying it utterly!
