Defense Task Force

Defense Task Force is a tower defense game in which you command the defense of energy-harvesting platforms built to power Earth. The alien Kraken attack in procedurally generated waves, and you use resources to build fortification towers and protect the platforms. The game includes a 20-mission campaign across five regions, each with four sectors, as well as an infinite-waves mode.

Missions and environments

Missions take place on a rendered planet with procedurally generated terrain and weather. Each mission’s layout depends on the blueprint you research and deploy, and you can also choose its planet region and sector. Enemy waves are generated procedurally, so their composition changes between playthroughs, including when you replay a mission. The campaign is non-linear, with multiple ways to approach each level; after winning a mission, you can move on or keep playing to survive as many waves as possible.

Towers and research

You can deploy 10 tower types, each with its own attack behavior and three upgrade levels. Third-level towers can also receive individual attribute upgrades, such as improved rotation speed or damage. Tower upgrades, global skills and blueprints must be researched before use. You spend energy earned from winning missions to unlock regions and sectors and research technologies, blueprints and upgrades. Your research choices shape the strategies available, and the towers have complementary roles rather than one being superior to the others.

The Kraken

The game features 25 alien enemy types, plus three additional units spawned by other enemies. Their classes include Regular Units, Swarmers, Racers, Cloakers, Healers, Boss Units and Spawners. Enemies differ in speed, hit points, shields, strengths and weaknesses against tower types, and special abilities.
