S.H.M.U.P puts you in command of up to fifteen independent ships, defending your wall against a never ending collection of enemies and massive bosses. To aid you in your defence, you have access to a plethora of upgrades and awesome exploding, homing missiles. S.H.M.U.P features chip tune inspired music from Bart Klepka (http://www.myspace.com/bartklepka) and Multifaros (http://multifaros.info.se/). The game also features a Twitter integration (which was included months before any commercial game announced it!) and extensive modding capabilities.
