I've been playing the Planetside 2 beta 
The most epic FPS game there is. The only game where I can look over a battlefield and see hundreds of players fighting in HUGE battles 
Looked into the game and it looks pretty awesome! How do you go about getting the beta? Is there a way to get it without buying the actual game?
well first of all believe it or not, the game will be FREE TO PLAY!! and I got into the beta because I played the original planetside (they let original players into the very first wave) the easiest way to get into the beta is spam their twitter account with messages

they are always giving out keys on there.
Also the game is very demanding, you'll need a fairly hefty computer (I can play battlefield 3 seamlessly at 60fps, i get about 40fps in this game and around 25fps is huge battles), but optimisations are coming!! its more CPU intensive than anything if you have an i5 or something similar you should be good :)
