“We are now over the hump with our third major content patch, and are well on our way to including most of what we wanted with Rogue Legacy 2. We still have a few surprises in-store for future updates, but the Drifting Worlds marks a milestone in our development roadmap! From new features that extend replayability, to massive optimization work, weve got a ton of things in-store for this update. Chief among them is the opening of the Drift House, a curious dwelling that holds the mysteries of both space and time. Theres also a host of new content including classes, traits, skills, and a brand new biome to explore, the Sun Tower.”
