Japanese logic: guns and rockets cant dent the monster, but a big knife will cut its arm off. Not a bad trailer though.

@warhawk-smakaho Have you played ACIII ? The ship missions are incredible (actually the best part of the game in my opinion). Anyways, i'm sure you'll have plenty of opportunities to stab people in this one as well, I mean, it is Assassin's Creed after all.
