Xbox 360

The Ultimate Doom, named simply Doom on the service, was released as a download for the Xbox 360 on the Xbox Live Arcade service on September 27, 2006 for 800 Microsoft Points, ultimately getting its price halved to 400 Microsoft Points ($5 US). After Microsoft points aren't able to obtain anymore, it's now € 4,79. In September 2010 the game was delisted from the service catalogue however it was subsequently put back on the marketplace. A one-level trial version was also available, including the first level of episode 1. The port was developed by Bethesda and Vicarious Visions.

A matching port of Doom II was released on May 26, 2010. This port includes a new episode, No Rest for the Living. The Doom II port and new episode were also developed by Nerve Software. The Doom II port is priced at 800 Microsoft points, but later halved to 400 Microsoft points (now € 4,79).

On November 2014, Xbox 360 has reached 7,000 video games, with the GameFAQs updated.

Doom
The game was initially published by Activision, but it was replaced by a version published by Bethesda Softworks, however the Xbox 360 port of Doom has been delisted again, since the 14th of April, 2013, and is now impossible to legally download, unless it was purchased before it was taken down. However, a streamlined version of this port along with Doom II was included in Doom 3: BFG Edition.
