The epitome of "fine". Shooting is decent and the powers are cool but the story is lame, combat encounters in the later half are weak, and they limit your usage of the powers too much for you to really have fun with them. I think I had more fun using the speed and cloaking to skip encounters than actually fighting. There were also plenty of annoying bits like anytime you're chased by a helicopter and didn't keep a missile launcher just in case and most of the alien fights seriously overstay their welcome. The game usually keeps a good pace though and the human fights can be enjoyable when you're not needlessly overwhelmed.
