About This Game

Command the last outpost on a hostile space frontier in this compact strategy game. Waves of enemy ships sweep along a fixed route toward your central spire, and your job is to plant defensive structures where they hurt most. Every destroyed attacker refunds energy, the currency you reinvest into stronger turrets and clever upgrades. Choosing when to expand and when to reinforce is the heart of the challenge. Fans of tactical planning who like short, satisfying sessions will feel right at home here.

How to Play

Pick a defensive structure, then click a spot beside the enemy path to build it. Each construction costs energy, and destroyed ships pay you back. Use mouse, keyboard shortcuts, or touch taps to place, sell, or upgrade towers. Survive every incoming wave without letting your main tower fall, and clear all levels to win.
