Hey. I was so lucky i got a dota 2 key through a friend today because he has to go to india for ½ a year and wouldnt use it anyway. But he forget to tell me where to register and DL client. Can someone help me a little here
DOTA2 invites are done all through steam. Unless for some reason your friend got a key in a weird way, he will gift you dota2 beta in steam and you will do everything there. AFAIK there are no actual "keys" in the traditional sense
