Alongside DOOM II and Voodoo Dice, a third downloadable game--Ben 10 Alien Force: The Rise of Hex--sneakily appeared on the Xbox 360 with little fanfare today.

Priced at 800 Microsoft Points / $10 with a free demo available, the Black Lantern-developed side-scrolling platformer offers fifteen levels and ten alien forms for puzzle solving, all inspired by the television show. A downloadable WiiWare version is due by the end of May 2010, according to an April 2010 press release from publisher Konami.
