Wasteland is another Arma II mod that pits you on teams against other players in Chernarus. Random objectives go to each player and you will find NPC's and weapons crates and ammo. You use cash to buy more weapons as you and your team wonder Chernarus. You establish and defend bases from two enemy teams and complete objectives to gain more equipment or cash. Have a great team is a must in order to be greatly effective. It is like Battlefield on a much larger scale, and more hardcore. This mod is already ready to play if you have the most recent beta build in the Arma game. You will need OP Arrowhead and the first Arma II game. You simply set the filter to Wasteland and then you can play!
