Back in October 2010, Activision's rights to the classic 1990's shooter DOOM expired, forcing them to from Xbox Live Arcade.
Fans of classic games can rejoice, as DOOM has returned to XBLA, thanks to the rights now fully belonging to Bethesda Softworks, who promised at the time that the game would return "shortly". That turned out to be a 15 month wait.
The Xbox Live Arcade version of DOOM features same-machine, four player split-screen multiplayer, Achievements, and costs a paltry 400 Microsoft Points. DOOM II is also available on XBLA, for 800 MSP.
DOOM was originally released on XBLA on the 27th September, 2006. The original PC version debuted back in 1993.
