The earlyer version got game of the year back in 2001 i herd.
It is the most realistic warfare game i ever played and the maps are great in size and with hills wich you can snipe camp and flank on.
It has choppers tanks apc and armed jeeps.
The multiplayer goes up to 32 player slots for infiltration and anialation, and 4 players for coop, and runs smooth as a babys bum unlike arma2 and controls are basic unlike arma2.
Also there are a lot of custom mission maps being released by clients and also a few mods.
Pretty popular game to it seems, always plenty of players online.
You can also host an play ranked games or unranked to your choozing.
I give it a 8 and a half out of ten as its not a repitituos game but cruizy gameplay and i hate repitiuos call of duty series lol.
