Altogether not that great. There are only 3 types of game you can play. At first it is fun, but after a while it gets a little tired. Also because of the enormity of the maps, people can just take a sniper rifle to the opposite corner and pick people off, which kind of takes the fun out of it.....
Its a single player game. The multi was really just thrown on so they could print it on the back as a feature. That said, its still awesome in single player
