If your an Id software fan then this won't let you down. Its a great FPS, with great weapons and gadgets, really cool looking graphics and some of the best gunplay you'll find in a FPS. Every level/ enemy group is different to fight. Id know what they're doing here. For the price its well worth it, you'll have fun here. The co-op on disc 3 adds up for some fun times with mates. The ingame racing and vehicle combat are fun too, and a good break from shooting stuff. The down here is the story isn't the best, but with a game this fun/ good looking I don't play it for the story.
