Steam has revealed that along with the new Mad Max game you'll be able to buy all four films, from the 1979 Mel Gibson original to this year's Fury Road. Valve does very little promotion for movies on Steam, but said in a press release that it has 100 titles to date, which sent me scurrying to check that fact. And yes! Sort of. There are titles for sale, but all are either documentaries (including its own) or straight-to-video fare like Let's Ruin it with Babies and Kung Fury.
