A lot of people are curious about how Overgrowth's map editor system will work so Wolfire recently released a video to show off all of the Phoenix Engine's latest editing features. The video includes a tools tutorial, timelapse building construction, and exclusive footage of the elusive Rabbot. Although Overgrowth is still in the early alpha stages, fans were excited to see how much functionality has already been added.
