Tideguard:The Gyrekeeper's Oath

Tideguard is a tactical, ocean-themed tower-defense where you play as a Gyrekeeper protecting the Great Gyre. Build mechanical and biological towers, plant restorative reefs, and use cleanup magics to keep pollution from reaching the heart of the current. Track pollution, react to sudden disasters, and follow a 20-level campaign as you discover the source of the dumps and shut down the Maw. Clean the tide, save sea life, and restore the currents.
