TerraTech Legion is an action game from Payload Studios that puts you in control of customizable vehicles to fight an AI invasion threatening the galaxy. As a Tech Priest, you must destroy Legion bots, outposts, and factories on multiple planets before they turn the worlds into techno-organic wastelands. The core gameplay revolves around building and customizing your vehicle with modular components such as wheels, boosters, chainsaws, and orbital lasers that directly affect movement and combat capabilities. You’ll face waves of enemies as you explore maps to find and destroy Legion factory outposts, culminating in boss battles against brutal mechs and planetary overlords.
