Can You Play Original Xbox Doom 3 on Xbox 360? No—But BFG Edition Available

You cannot play Doom 3 for the original Xbox on an Xbox 360. The Xbox 360 is not backwards compatible with original Xbox games.

However, there are options to play Doom 3:

• Play the PC version: Available for PC; you could potentially play on Xbox 360 if you have a compatible PC and connection method.
• Get the re-release: Doom 3: BFG Edition is a remastered version available on Xbox 360 (and other platforms). It includes updated graphics, a new single-player chapter, and the original Doom 1 and 2.
