Invasion

You control a stationary turret at the bottom of the screen, using your mouse to aim and fire at incoming units. The main objective is to stop them from reaching your base, which sits behind your position. Each wave introduces different enemy types, some moving faster or taking more hits to destroy. You earn money for each kill, which you spend between rounds to upgrade your weapon's damage or firing speed. The pacing is relentless; the waves come quickly, and a single breach often means the end. It feels like a constant, tense scramble to keep up with the advancing line.
