2112TD: Tower Defense Survival

Set a century in the future, this sci-fi strategy game pits you against interdimensional flesh spawn across the solar system. Your mission is to defend Earth's colonies from complete annihilation by building, deploying, researching and upgrading your defenses around a mobile command center. The pace is steady but the stakes are high as relentless hordes amass to overrun your position.

Unlike traditional tower defense titles, success relies heavily on micromanaging dynamic action-based abilities. As you push deeper into the campaign, airstrikes, charged attacks, fortification walls and the tactical drone become increasingly vital, and deploying them strategically is paramount. Mistakes are punished, so learn from your blunders and endure to fight another day.

The art style draws on nostalgia for the RTS golden era, paying homage to classics like Command and Conquer and StarCraft. Deploy machine gun, flamethrower, artillery and plasma turrets, then upgrade them to experimental stages packing serious firepower. Air support delivers the big boom when situations get hairy, while Earth's researchers unlock new abilities and weapons as you progress.

A tactical database gathers battlefield data on your arsenal and enemies alike, and checking it often is critical to triumph. Beginners find forgiveness on normal mode, while veterans are drawn to hard, nightmare and survival challenges. There are no in-game advertisements or microtransactions, and the game can be played offline. How long can you hold back the hordes, commander?
