If the game listings on the ESRB ratings website are to be believed, then we could be getting Final Doom on our Xbox 360's sometime soon.
Siliconera was the first to spot the listing on the ESRB website, which shows Final Doom being listed as an "M" title, along with Ultimate Doom, which was already released on to the Xbox Live Arcade last year.
Final Doom is based on Doom 2 and features an additional 64 maps of mayhem. So while we can't confirm the game is coming, don't be too surprised if it does pop up. We'll have more information and updates for you as they arrive.
