The Dishwasher: Dead Samurai, James Silva’s bloody, combo-centric slash ’em up platformer, is coming out today (April 1st) for XBLA… for 800 points ($10). The game, in which you play an undead dishwasher/samurai, features a unique co-op mode where players can use a guitar peripheral to rain electric death upon their enemies.
James has also released a book on XNA titled Building XNA 2.0 Games: A Practical Guide for Independent Game Development, which details how he created The Dishwasher alone in a year and a half.
