This fall, Xbox Live Arcade doubles down on Serious Sam. Serious Sam 3: BFE - which launched on the PC late last year and was ported over to the Mac last month - will ditch the disc for an Xbox Live Arcade release this fall. Serious Sam 3: BFE on XBLA will be the full game, losing nothing in the transition over to console.

Serious Sam Double D XXL is the new version of Mommy's Best Games' PC release. The XXL brings with it "new campaign missions, new challenges, new enemies, Gunstacker upgrades and a hot new two-player local cooperative mode." Serious Sam Double D XXL is priced at 800 MS Points ($10).
