Star Defense : Frontier

Command the last line of defense in Star Defense, a sci-fi tower defense game set across an orbital frontier. Guide a growing team of operatives through a 30-stage campaign spanning three star sectors. Deploy units beside enemy routes, protect the energy core, and survive each wave of attacks. Choose where to place each operative, earn resources by defeating enemies, and upgrade your team during combat. Each operative brings a distinct attack style, from precise single-target fire to area damage and slowing effects. Explore the campaign map, unlock new operatives, train their abilities, and review enemy intelligence as you prepare for the next mission. Adjust the challenge with three difficulty settings, pause or speed up battles, and revisit your results in battle reports. Your command starts now.
