Much better than I expected...
The missions are pretty long and are mindless FPS ecstasy. It's been a long time since I played a true run n' gun game and this one doesn't dissapoint in that way. Where it does fail however, is in the enemy AI. They mindlessly shoot at you without care for there own lives. The sword-fighting, much touted before the game was released, is a huge letdown. No skill is required to mercilessly slaughter your opponent-just flick the wiimote and eventually he'll go down.
The multiplayer, however, is quite good. With enough maps and standard-issue modes to keep you happy for a while. It's a real joy to compete against someone else using the wiimote. Thanks for reading!
