5 True open world war simulatorVangu4rd | 14/10/2009 | See all Vangu4rd's reviews (1)ARMA 2 is the only true open world war game on market at the moment. You can play everywhere on a huge 225 square kilometer terrain and create infinite amount of different scenarios in the mission editor. (You can have hundreds of units from different factions fighting simultaneously.)With the latest 1.04-patch the game is stable and mostly bug free considering the overwhelming size and scope of the game.ARMA 2 is best played with a group of friends on a realistic mission. It includes built-in VOIP and JIP (join-in-progress).This game is not your average corridor shooter where you move from checkpoint to checkpoint killing bad guys and then repeat. In ARMA 2 the missions can take hours (if you choose so) and you can use real military tactics better than in any other title release so far.
