Swedish developer Avalanche Studios powered their free-roaming action title Just Cause with their own Avalanche Engine, and now they’re taking it to the next level with aptly named Avalanche Engine 2.0. The newly completed engine features support for truly huge environments without seams, as well as advanced character rendering systems for animation, facial rendering, and emotional modelling to simulate human behavior. Well it certainly renders some killer rocks. Perhaps they’ll show something a little meatier at the Tokyo Game Show this weekend, where Avalanche 2.0 will make its worldwide debut.
