im thinking of buying shellshock live and i am wondering if i should buy it now or are they going to put this into the summer sale. also if i buy the open beta will i have free access to the official game when it is out?
It's probably best to wait until the summer sale since it's only a few day's away from starting (23rd). And there is no harm in waiting a little just to get it at a cheaper price too. Once you purchase the game, you have access to it during, and out of beta forever no gimmicks.
Keep in mind it's not a guarantee that the game will be on sale. This is what I like about Steam and digital game copies
