how can i play steam games before release?

Answer 1

have an army of computers, a few hundered would work and break the code for the encryption, which was used to stop people playing early, so its possible, but not easy, doing it on lets say 20 top end computers wouldnt manage it in the few days you have to wait

in short, dont bother, you cant access enough power to manage it

also thats more of a hacking question than a game question
