Can you really picture a group of masked revelers gathering around a cake or giving the bumps? We can't. Not unless it was part of a cunning plan to off the daimyo with a glass of poisoned Cresta or an explosive party bag. No such excitement at the tenth anniversary event for stealthy ninja franchise Tenchu – just a new game announced, and a Wii exclusive to boot."
