A good first person shooter for a cheap price.
There are a wide variety of guns and things to pick up, such as chairs and bottles to throw at your enemy.
There are health kits all around to make sure you don't lose too much.
You can open lots of doors and there are lots of places to explore.
The A.I. is pretty good and the main character sort of looks like Bond.
I bought this game for $8.98 brand new, but you could probably find it cheaper and I suggest any one looking for a good underrated game should pick this one up.
