In the face of an alien encounter, earth's defenses are breached, and the enemy has begun to invade. Players assume the role of a defense commander, responsible for restoring order and launching a counterattack against the extraterrestrial forces.
The gameplay revolves around strategically placing towers and surgical strikes to thwart the alien advance. A key mechanic is the dynamic progression system, where each level's failure builds on previous lessons, presenting increasingly difficult challenges. Certain areas have particular weaknesses, requiring attention to which areas should be fortified.
The objective is clear: halt the invasion and reclaim the planet. With levels ranging from small skirmishes to full-scale battles, it becomes apparent that mastering the surest points of attack will be essential to halting the evil invader.
