It's fun on it's own, if you pretend the first Crysis never happened. Which essentially it didn't because of how little this relates to it. The gameplay is greatly dumbed down from the first Crysis to be more like Call of Duty. It is never fully explained what happens to the original characters either. The aliens went from blue squids with squid like vehicles that used ice weapons and an ice sphere that could take out an entire island in less than a day to red jelly blobs with Transformers suits, Halo like vehicles, that use plasma like weapons, and a rather slowly spreading virus. (No explanation to why they changed either.) It just didn't feel like Crysis at all. The last thing I'm going to mention is that the soundtrack was great.
