Chat with Devs: Something I noticed during our recent shows at Games Convention in Leipzig and PAX in Seattle is that many new players trying out the game who played Zerg built several creep tumors, thinking they were either defenses or going to morph into defenses. This eventually lead into a conversation with Dustin about why Creep Tumors no longer morph into base defenses. For those who dont know, a Creep Tumor is a building which expands creep around it significantly. Building this building is an excellent way to cover additional ground with creep, allowing for many new strategies, including aggressive Spine Crawler pushes (the mobile Sunken Colony).
