If you are a veteran of BF2: Project Reality mod, Arma, Insurgency, or any of the more realistic milsims, this game is for you.

If you are coming from the Call of Duty, Battlefield, or Counterstrike communities, read the guides first, ask questions in voice comms, and learn a bit about the game before you get put off. The game is heavily focused on teamwork and tactics. It has 1-4 bullets to death ratio. Do not make the mistake of trying to treat it like an arcadey shooter. You are not going to get anywhere charging an enemy base by yourself or lone wolfing it. Join a squad, stick together, and most of all, communicate. Losing can be fun if you do so while fighting a desperate holding action with your squad.
