The good news: 2 hours ago, Samurai II: Vengeance appeared in the Android Market.
The not so good news: the game is carrying the tag THD (Tegra HD), meaning it is optimized for Tegra-based Android devices only, according to its description. This means the XOOM, the Adam, the gTablet, and the Atrix are pretty much the only devices capable of running it properly right now, but with the advent of Tegra devices this year (the Bionic, 2x, gSlate, and others), we should all get a fair chance soon (hurry up, Sprint!).
Update 6/24/11: The game is now available for all devices as opposed to just Tegra-powered! You can find this new version in the 2nd widget towards the bottom.
As for the gameplay, I'll let the video do the talking. Be prepared - it's bloody... mighty bloody.
To say that I'm jealous of Tegra-powered device owners right now would be an understatement. Where's our XOOM, Moto?
