I get Alpha key but my Pc no good...I hear its only for Pc and Im really angry...Why only for Pc and not consoles anyone can answer ????

Easiest to put on, they'd need to get permission and possibly pay where as for PC it's much cheaper and easier. The beta will be multiplatform.

They need to pay a lot of money to put the alpha on consoles.

PC is easier.

There will be an Open Beta closer to game release.
