The single player is a short game / long movie...why a movie? graphics and story makes it feel like it is. Re-playability is good considering that this game has the best AI in a shooter I've encountered so far. Play it on easy to get a good grip of the levels and on the most difficult level to make it feel like you're actually playing against opponents that make it seem like there's people controlling them in real time. Multi-player...well I'm sure you've already heard that the multi-player is awesome and you probably won't be putting the game down for a while. Jhov I'll add you soon so we can kick Higs or ISA's...to anyone with a PS3 playing multiplayer, my SN is Rammyboy.
