Union of Armstrong

After valuable minerals were found under the Apollo 11 landing site, the Luna Mining Corporation began tearing down this historic landmark. Enraged by this behaviour, some colonists declared their independence from Earth called themselves "Union of Armstrong" and began defending the landing site. Union of Armstrong is a tower defense game. The company forces move towards the base and the player needs to build towers to kill them before they reach their goal. The overall power is divided into three pools: resources (used to build towers), defense (drops when the base is attacked; reaching zero ends the game) and power (slowly drops with each built tower; the towers' efficiency decreases when it reaches less than 100 points). Power points can be moved between the pools. The three available towers are basic, advances (can fire in four directions) and slow (slows down enemies).
