So if any of you haven't tried this yet. YOU SHOUD! Even though the graphics aren't all that good. The gameplay is amazing. The ballistics mechanics are very real. The whole game itself is realistic. And the battlefield is huge! It's hard to explain. The game comes with a 14 Day free trial and then you can either pay or do a Free 2 Play where you stay as rank one.(You can just keep making multiple trial accounts). There is quiet a bit of teamwork. Also don't fly the planes without a joy stick. It's almost impossible.
