Hi, I'm planning to get this game or the future Arma 3 solely for testing out the mutliplayer gameplay. Can any seasoned players give any tips on how to behave and conduct myself when fighting in a match. I definitely have grown sick of every other FPS out there (no bullet drop; shot 50 times and still standing). I'm a little uneasy though of how well I'd fit in when I finally get this game.
