for some reason there are only a few games based on the vietnam-war...
i've played the vietcong MPdemo and i liked it... but i guess u probably did also... i can't give u any more details about the full game....
but also in the same period the vietcong-demo was released a friend of mine gave me the full game ; Vietnam - Line of Sight...
IMHO this game is awesome !!! i know u can't compare a demo with a full game but i couldn't read this topic without mentioning there is another great vietnamwar game available at the moment...
u can find a demo here...
hope i don't make it more difficult for you, Sgt
