Tower Defense for 0 A.D. is a strategic mod designed for Windows that revitalizes the classic tower defense genre within the 0 A.D. universe. Players can engage in a challenging gameplay experience by defending their base against waves of enemies. The mod includes two maps: a single-player map and a multiplayer map for two players, focusing on strategic tower placement and upgrades. Players must choose the right tower types and positioning to effectively fend off invaders, making tactical decisions as they progress.

As players eliminate waves of enemies, they collect loot that can be traded in the market to build and upgrade towers. The mod introduces new templates for towers while maintaining compatibility with existing game structures, allowing for easy integration. Future updates are anticipated to include balancing adjustments and new features, such as the ability to heal the base structure. This mod promises a fun and strategic experience for fans of tower defense games.
