Original Doom 3 pulled in wake of BFG Edition release.
The original version of Doom 3 has been removed from Steam.
The game's removal follows the launch of Doom 3: BFG Edition, the updated version of id's horror shooter which released last Friday.
The original Doom 3 had previously been available to purchase on Steam for £13.99. Doom 3: BFG Edition costs £19.99.
The BFG Edition does, however, include additional content, including updated visuals and Doom 3 expansion pack Resurrection of Evil. The original version of Resurrection of Evil has also been pulled from Steam.
Unlike the original, though, the BFG Edition lacks mod support - something that will come as a disappointment to many PC players.
The original Doom 3 is still available to purchase in the Super id Software Pack, though. That costs £75.99, but is often reduced in price during sales.
Reasons for the original Doom 3's removal have not been provided by Bethesda.
