This year's Steam Summer Sale broke records, and it seems many developers have benefitted. Among them are Introversion who's Prison Architect passed the 2 million copies sold milestone (on PC, Mac and Linux) as a result. The developer announced that it has generated more than $25 million to date.
Prison Architect launched on PS4 and Xbox One the other week, and while no numbers are released yet, Introversion said they "can't wait to find out how many console gamers are going to be bitten by the PA bug".
