the game was good up to the point where mutated monkeys (wtf is up with that) that take a clip and a half to put down started coming out of the woodwork. Next, mutated mercenaries with rockets (wtf is up with that) started coming out of the woodwork. They could take a rocket blast and still be up for more. Very cheesy.
Bottom line is:
Great gaphics and AI
Good gameplay up until the stupid mutated monkey bull$hit
Convoluted storyline that screams "We had no good ideas after the mercenary stuff and just made up so goofy $hit that doesn't add one iota to the story."
The MP is okay if you're playing with friends...
