Priced at 1200 Microsoft Points ($15), the downloadable Xbox 360 release supports up to eight players over Xbox Live, and up to four players on the same Xbox 360 console. Try to imagine Worms without the restrictions of turn-based combat--that's Death Tank.

Originally a hidden game within Lobotomy Software's PowerSlave, released for the Sega Saturn in 1996, Death Tank allowed up to seven players to rain destruction upon each other and the surrounding randomized landscape. A second version, Death Tank Zwei, was hidden within Lobotomy's 1997 Saturn release of Duke Nukem 3D.
