Gamespot: "Let's face it, the PlayStation 3 is sorely lacking in the ninja-action department. There are racers, shooters, sports games, and action games, but ninjas? Not so much. Thankfully, Tecmo's Ryu Hayabusa is slashing his way to the PS3 in Ninja Gaiden Sigma, a new take on the Xbox installments in the series, Ninja Gaiden and Ninja Gaiden Black. The game was announced last year, when it was shown off in flashy trailer form at the 2006 Tokyo Game Show, but we hadn't been able to get our hands on the game until recently, when Tecmo stopped by with a work-in-progress version of the game for us to try."
