The finest railgun in the business will be making its way to Xbox Live Arcade as id announces Quake Arena for Microsoft's download service. Previously, this release was merely a rumor fueled by a surprise listing on the ESRB website, so it's great to finally have an official word to go on.

Also true to the ESRB listing is that Pi Studios -- best known for their work on the Call of Duty series and the upcoming Mercaneries 2: World in Flame -- is behind the port.

No comment as to when Quake Arena will see release was made by id.
