The Greenlight Supershow is a 13-hour webshow event on Twitch that will have live gameplay and discussions with developers. RobotLovesKitty, the makers of Legend of Dungeon, are putting this show together to help a bunch of indie games draw more attention to their Steam Greenlight campaigns. Check the schedule on the Supershow website to see what games you are interested in.
Each game will have a half hour time slot. Retrobooster picked up the 10:30pm slot (Eastern Time). Watch the stream to see what it's all about, and then head over to Retrobooster's Greenlight page to vote for it.
