I enjoyed this game alot. I'd say it was better than the first, except I haven't ever played the multiplayer on the second. I still liked the game though. I think it had better levels, better graphics, and a better plot than the first.
You will be subject to gruelingly slow frame rates. I will not hesitate to drop you below 20 frames per second. I will blur the graphics until your eyes hurt. You will play bland level after bland level without so much as a whimper.
