I was really loving this game..."was" being the key word here.
The game got insanely retarded when you enter the other world. It even got really hard really fast. The spider/crab boss that you have to kill is just difficult as hell. It's not even the boss that's really all that tough. It's those damn little baby crab creatures that look like dead roasting chickens that pissed me off. It's a pain in the butt to try and shoot these things all while trying to defeat the boss. They are relentless. I finally used the invinsibilty cheat code to get past it. (Note: I rarely EVER use cheat codes) I figured whatever was next would be cool. I was wrong. It just got even lamer. I don't even know if I'll finish the game. This game should have ended in the real world. Either that or they could have made the alien world a hell of a lot better. What really pisses me off is that I was totally loving this game. Up untill the point I just described it was one of my favorite games ever. I'm truly disappointed. It's gonna be tough to rate this game based on what happens to this game towards the end.
If it weren't for the alien world I'd probably rate it a 9.5, but because of the alien world I'm giving this game a 7.
