Play as scrappy rodent engineers fighting back against elemental predators. Build mazes with complete freedom, place towers strategically, and dash through your own defenses as you battle waves of enemies hunting you down.

- ▸Elemental Combat: 4 base elements + 6 hybrid combinations
- ▸Co-op First: Designed for teamwork, not just scaled difficulty
