Project IGI 2?

I've played Vietcong too. they do about as much as they can with the Vietnam setting. Obviously it's a bit limiting, you're either in the jungle or down a rabbit hole. However you do get to be a gunner on a helicopter, and a gunner on a patrol boat, you get to be a tunnel rat, fall into spike pits,  engage in night fights and call in wicked air strikes and even fall into an underground gook latrine for your sins 8O

The enemy AI is extremely good. Charles almost never sticks his head out and has the sneaky habit of flanking you when you're hunting  him. I was regularly on the receiving end of a bullet in the back of my head.
Graphics are good and the jungle looks pretty realistic. It's very questionable in it's treatment of the North Vietnamese people but who gives a crap...it's a great game.

One of the things I did like about Splinter Cell was the challenge of completing a level without firing a shot. it can be done on most levels but is damn hard sometimes. Made it quite like Thief though which is no bad thing.
