Just join the Steam community group at Steamcommunity.com and you have the chance to win a free copy.
We will give away another free copy to one random player who is a member of the Zeit² Steam group and uses one of the Zeit² avatars as their user picture. So join the group and make one of the brand new Zeit² avatars your profile picture to double your chances.
Spread the word to your friends and have fun playing Zeit²!
I joined the steam group, hope I win :)
