Core Defense 2099

Core Defense 2099 blends classic tower defense with direct hero combat. In the year 2099, you don’t just watch the map—you fight, build, and adapt as enemies flood the grid in ever-tougher waves.

Gather resources, place turrets and support structures, and upgrade your strategy while your hero slashes, shoots, and sprints across the battlefield. Face boss encounters with unique pressure patterns, juggle economy and ammunition, and push your loadout to the limit when the warning siren hits: something big is coming.
