About Space Tower Defense
Space Tower Defense is a tower-defense game set in space, where enemy forces swarm toward your base. You command its defenses, building and upgrading installations within limited space and resources to withstand successive waves of attackers.
Adapt your defenses
Enemies detect your defenses, give warnings and try to bypass them, so you must adjust your deployments. Towers have different functions and can be combined to suit your strategy. Each map has its own routes and nodes, and your choices shape the battlefield.
Face stronger waves
Enemies grow stronger and smarter as the waves progress. You must upgrade your technology to survive, while balancing your placements across the map; a single tower is not enough to secure victory. The game presents its space combat with sci-fi visuals and audio.
