I'm terrible at this game with the gamepad, just can't seem to aim properly, and with the Wii remote I have no idea how to find that sweet spot with the calibration. Looks like I'll have to get a Pro controller before I can really sink my teeth into it.
I played the first couple of campaign missions, one round of zombies, and three rounds of multiplayer. MP ran smooth as butter, there was only one moment in the second campaign mission where the game like randomly started spazzing the fuck out, but other than that I'm perfectly okay with the graphics and framerate.
Really the only negative for me so far is that Oscar worthy story. It's really boring, I couldn't care less as to what's going on. But then again I didn't beat the first one so maybe that has something to do with it. Stories in these games... lol
