Popcap, the people who have been bringing you the best in casual game for years now with Bejewled, Peggle, and Plants VS Zombies, just announced their new experimental game label, 4th & Battery.The new label will be focused on experimental game design, smaller, and edgier games. The quotes from inside Popcap are saying that the studio is designed for the developers who are stressed to take some time to blow off some creative steam by making games for 4th & Battery. Their first game has been teased, but we don’t know what it is for yet. It’s called Unpleasant Horse and has you pushing nice horses into a meat grinder for points. Check out the teaser trailer below.
