Butty I wouldnt bother mate.
Thats battlefiled Vietnam, this is my favorite game of all time, and I play it extensively, but its purely an online game mate and youll not get an online key, there is a FPS game on there but its shit and the AI will stand there shooting in the air and stuff, they fly helicopters like a pendulam swinging, its good jumping into a hue and missiling the shit out of every one but that game is purely made for online play, best to buy it and well fooking worth it, best 25.00 I ever spent in my opinion buying BFV ive had weeks of none stop fun on there
This one thats due out though is going to be even better
Ive got on CD someone Battlefiled 1942 with codes too, I'll see if I can route them out and send you them, save you downloading it and give you a slight idea what vietnam will be like.
Personally i think vietnam is far better but 1942 is set in the deserts / gulf and is the gulf conflict I think
Vietnam is exactly what it says oon the tin, and BF2 is now adays, and its going to fooking rock the world mate
