Alien Defense

The game is very simple, you have three guns, which should protect the colony. A colony of heaven attack flying objects to be destroyed. Given that your torpedoes can cause damage to the enemy only fragments, you have to shoot on anticipation and hopes that the enemy will fall into the zone of fragments. Number of torpedoes in each cannon is limited, they must be used wisely. To move to the next game level, it is necessary to repel the attack. If during the attack you lost a few guns, the next level will have to start with the rest.
