Ive played the PS2 version and its good fun. Its kinda scary at time sbecause you never have a great deal of ammo, and surprise attacks are common place which leaves you desperate for ammo for bigger baddies.
The team mates trust/fear factor adds a nice touch. i tested a guy to see if he was a thing, and he wasnt, he fell out with me over it and refused to follow orders. i killed the bugger in frustration, which caused my other team mates to panic and shoot the hell out of me. bastids.

Its a game well worth a look even if your havent seen the film.

but sorrynewt i dont have a scooby how to solve your problem. but if you have warezed it like sclass says, then do yourself the favour a nd buy the sodding game!
