Don't let the "multi-platform" thing fool you. Skulls is 100 percent a Microsoft exclusive. You'll simply be able to play it on anything that runs Windows or some approximation of it. Xbox Live Arcade, yes, but also Surface tablets, Windows Phone devices, and Windows 8 PCs via the new operating system's app store.
As you might have read in our earlier previews or our recent Joystiq Indie Pitch, the 10-15 hour campaign casts players in the role of a recently deceased samurai lord from feudal Japan. Horrified at being forced to wait in line for half a millennium before being admitted into the afterlife, our General Akamoto takes matters into his own hands. He enlists an army of zombie Ronin to fight by his side and sets out to carve his way into the great beyond.
