Doomsday is an experimental/casual first-person puzzle game. Assuming the role of a "sidewalk prophet" you must convince bypassers that the end is nigh. By targeting them and choosing a three-button combination, you need to create a large enough following in 70 seconds to prepare for annihilation. But what happens if nobody believes you? Are the end time really upon us? This game is best played on an XBOX 360 controller on PC but supports keyboard play. Controls are Space/A, 1/X, 2/Y, 3/B. Play/Start and Quit/Back also are used for the title screen.
