The best multiplayer shooter on the whole World
Yeah driviable vehicles and more maps, i think AA is the best game and it will be the best everytime. It's totally free game and it's not only multiplayer FPS it's the best FPS you've ever played. The comunication in the game is very simply when you download TeamSpeak and if you have a microfone of course. I love this game. It's slow-paced, rewards brains over fast-twitch brawn, requires teamwork between strangers.
Team play is emphasized and important once you enter the online games. Its not just about killing the enemy but also completing mission objectives and watching your team mates backs. My advice is to play as a team and do not try and finish the level solo. It really is supposed to be a team game, and there is no "I" in team.
In a few words: YOU HAVE TO PLAY THIS GAME.
