R3n's right about repetitiveness. However it's still a fun/tough game. Don't play hard or MAX when you start out. Go for medium or Easy. I started out at MAX, so each zombie swipe was like 40 dmg. And their hella lot tougher. Got sick of the game too fast after it got kinda frustrating.

Medium's just nice for me for the mean time. I'm progressing through the levels quite an okay speed. Rarely dying. But I still think it's a good fps game. I heard the multi sucks though. Haven't tried that one out yet.

But the monsters and weapons are just awesome. The level designs are brilliant, except you can hardly fight outdoors, which was quite dissapointing. I expected more outdoor fighting if it weren't for the oxygen thingy.

I think the next series would probably be hell on earth or in Phobos or one of MArs'es moons.

nevertheless, I still think the first person game is still kickass. Except less shock-value please. But the fighting in the darkness effect is cool.
