The wait for nostalgia-hungry gamers wanting to play their favorite titles of yesteryear on the Xbox 360 can be interminable. The 360 version of Capcom's Street Fighter II' Hyper Fighting, originally announced in January, was delayed repeatedly before finally arriving on the Xbox Live Arcade in August. Fighting fans looking forward to the 360 edition of Ultimate Mortal Kombat 3, originally announced for the Arcade in March, are still waiting for the game to arrive.

　　Such was not the case for id Software's classic first-person shooter Doom. The PC game was announced for the Xbox 360 earlier today during Microsoft's X06 media briefing, and the game itself was released on the Xbox Live Marketplace almost simultaneously. The game is actually a port of Ultimate Doom, including that game's fourth episode, "Thy Flesh Consumed."

　　Nerve Software did the honors in bringing the game to the Xbox 360 and made sure to throw in a few features along the way. In addition to the mandatory achievements and leaderboards every Xbox Live Arcade game supports, Doom also has "enhanced graphics," 5.1 surround sound, and online or split-screen modes in cooperative and deathmatch flavors for up to four players.

　　Doom is available to download for 800 points ($10) and is rated M for Mature.
