After a few hours the game started to give me a headache. I can't really pinpoint it... The sounds, the music, the story mode, the multiplayer mode... Ack...
The story is silly. That's all I have to say about that. You may like it, but I didn't.
I wasn't a big fan of the other modes. (helicopter, driver, etc..) They should have spent the time improving the playability of the FPS in general.
The fact that you can't get to the next part of the level without blowing up a wall. Lame.
And last of all, the headache I got from playing the **bleep** thing. I think it was the sounds.
