I thought the game was pretty good. The greatest game ever created? No. It was defiantly one of the strongest FPS on the Wii. I liked the over the top feel of the game. It was like some bad cliched 90's action movie. You just have fun with it and nothing else.
I have the game, and it's awesome ...it's a shame though that High Voltage Software did not take the time to fix all those online issues (glitches, crashes, etc) but yeah, I still like it though. I can't wait for The Grinder
Personally I find some of the campaign levels a bit frustrating, but the online is great fun once you get into it
