You need to learn how to parry if you want to survive. Press X and the analog stick in the direction of the enemy when they glow red. Raiden will bring up his sword to block the hit, and then you'll get an opening to attack. You can get through most of the fights without taking damage this way
"and when PS3 goes down you have to change your bank account and the locks on your door."
-You can heal (B (360) or Circle (PS3) when prompted during Blade Mode). -Experiment with button input timing. -You can dodge back with X+A (360) or X+S (PS3) and if you add in a direction you do a dodge slash. -You can cancel the flying kick (Jump then strong attack when in Ninja Run mode) into a stealth attack. -Towards, towards weak attack is a launcher -There are also away, towards weak/strong moves as well as a towards, towards weak one (all powerful) -Use the lock on during every fight. Forget trying to adjust the camera during fights. -The game WANTS you to use Blade Mode, so USE it. Especially on large enemies.
thanks for all your replies, I know how to heal now so I got a lot further.
I still don't know how parrying works though. I'm under the impression I'm doing it right, but my character just dashes towards the enemy and does nothing. Even when I'm close, I get ripped apart. I guess I have to practice more, since it seems crucial when fighting against that robot dog.
