It involves the multiple houses of feudal Japan, the Gods taking revenge on their lazy decadence and the Warlord retreating when on the brink of total conquest because he believes mistakenly he has killed all his opponents. Of course, you control the small band of freedom fighters he overlooked, and your job is to clear the land of the Dark Warlord's influence. In other words, as in too many games, it looks like the pages of gnarled back story still come down to, well, Diablo. Hack and slash your way through the levels. You can assemble a team of four Samurai from a pool of seven.
Replacements teleport in and out.
Don't ask me how teleporting became part of the Samurai history, I'm still working on how magic spells got into this mythos. You have direct control over the lead character and use Plays to give the rest standing orders to attack separate foes, guard locations, gang up on a single enemy, etc. The AI is pretty underdeveloped in this early version, so it is unfair to judge how well the computer controls your mates. They did seem to change formations eagerly enough when commanded and generally followed their standing orders. It is difficult to tell from the four-level alpha I played, but it looks as if the designers will let you deploy your team to do more intricate tasks than simply attack or defend.
