This game is better than most movie games but not by a lot. It is a third person shooter. I didn't run into many glitches but the internet is full of sites complaining about how glitchy this game really is. As far as my experience I thought it was a decent game. It was very repetitive as you had to fight the same kind of enemies over and over again. I don't know how they could have changed this as they only could use the machines from the movie. This basically left you with, I think, four kinds of enemies and one level where you had to take out some spaceships. Also some of the enemies you have to attack from behind to take them out so moving behind them is important. While I was doing this I went out of the "battlefield" and died. That should of been fixed so that you could not get a back to the areas that are "out of bounds" or there should of been no "out of bounds".
With all of that said this game is worth playing through but only as a rent. It should only take you 4 to 5 hours to complete and has 11 achievements all of which are from finishing the game. The language in this game isn't too bad with a couple of D words but that's about it and no real blood or gore. Overall rent this game and do not buy it.
