The high frequency blade in Metal Gear Rising: Revengeance will be your and Raiden's best friend throughout this cyborg ninja action game. You'll get access to new weapons like the pole arm, a pair of tsais and a pincher blade weapon along the way, but each of those will always serve as a compliment to the main ninja sword. That is, you can be slicing with the HF Blade and then switch to, say, the pole arm for some ranged head slapping and then back to the HF Blade to finish off with a flourish. Very cool. By the way, the pole arm is one of the most clever and unsettling weapons I've seen in a game in a long time. It's made up for half a dozen dismembered robot arms that are actually holding one another end to end using some kind of robot rigor mortis or something. It bends when it needs to and stays straight when necessary. All things should be that flexible.
Also we have a breakdown of some of the tougher super enemies and minibosses in the game. The Mastiff is the gorilla-type enemy who takes so long to beat Raiden into the ground when he catches you in a grapple attack that it ruins the timing on everything. If you've knocked an enemy down and a Mastiff jumps on you, that previously knocked down enemy will be up, recharged and waiting for you by the time the Mastiff is done bashing your head in. The Raptor, Irving and Grads are ALL super annoying, but if I've got to pick one enemy to just get rid of and we keep the rest, that $*&@! Mastiff is the one to go.
