Worth the money. You'd think its just-another FPS if you don't try the split screen mode. Brilliant.
When I first bought this, I just bought it out of pure frustration of not getting my money's worth on the games that I've bought before it in the recent past. The single player mission was okay, it was a bit too easy but hey, it could be me you know. When I finished it, I lent it to a friend of mine and it was he who told me that the split screen mode is worth trying.
So I started playing it and in all honesty, play it to this day with my brother, friends .. you name it. Its just perfect: not too hard, not too over-the-edge.
I wrote this review solely to indicate that finishing the single player mission and leaving the game to rust doesn't serve justice to it, try the multiplayer mode and you'll be pleasantly surprised.
