[quote name='Reaperain']How does the 4 way thing work? Cuz lol...Im edging towards just buying it myself right now.[/QUOTE]
First, make sure you have three other people willing to buy it with you. Once you've done that, have one guy coordinate everything (receives the payment, buys the game, distribute the games to the remaining three people).
For our group, we basically sent money (~$11.24 + $1.00 for additional costs) to guy buying the pack through Paypal. Once he had the money, he proceeded to buy the 4-pack himself. Once that was done, he sent each of us a copy of the game via Steam.
I'm not sure how sending out games work since I was the recipient, but I'm pretty sure it's not that difficult.
I found adding the three other guys as friends on Steam helped with the communication.
