Whilst roaming the halls of Quakecon and shooting everything in sight (with a camera), our friends at BigDownload spotted a heretofore unannounced Xbox Live Arcade version of id Software's FPS classic, Doom 2. According to Shacknews, the downloadable title is set feature all of Doom II's content, in addition to a new episode, 4-player local multiplayer and the usual online shootery. You can also expect an exciting doubling of barrels over the original Doom -- both of the exploding and shotgun varieties.

Also spotted at Quakecon: a further proof of life from our long-anticipated friend, Quake Arena Arcade!
