New Builder Game, Aven Colony, Sets Release Date for End of July. Dan "R4LFlapJack07" Farnsworth Jr. June 6, 2017 Sci-fi city builder Aven Colony has officially set a release date, planning to launch on July 25. Last year, Evan described an early version of it as “SimCity in space, but with sand worms,” which is a strong pitch. While a beta version of Aven Colony had briefly been sold on itch.io, this will mark the actual, full launch of the game. Aven Colony is available to pre-purchase for $30 on Steam right now. Pre-purchasing will get you a 10% discount and access to a new sandbox map called the Cerulean Vale free.
