For the price of £49.99 or your regional equivalent you can purchase access to the game. It is still in beta and so obviously bugs will be present and some content unfinished but if you just can't wait, go for it :)

EDIT: Price has been reduced to £37.96 (or regional equivalent). Maybe even the devs thought that £50 for an early access was a bit insane :P

Check out the links on the right hand side under 'chat room' of this page. Get yourself immersed in the lore and then let the waiting begin ;)
