This is a space-themed shoot-em-up with a small tactical element. The player protects twelve different star systems from alien attack, with increasing difficulty.

The main game is controlled by simply turning the ship with other side of the screen and firing the laser weapon by tapping the other side.

The sector map is controlled by tapping the sectors around your ship to move. As the aliens are encountered in the sector map the game switches to the shoot-em-up screen.

If the alien forces reach the planets in the sector map, they will launch an invasion and all will be lost unless the attack force is destroyed.

The player can boost the ship by gathering bonus weapons, such as guided missiles, extra shields and warp keys. As the alien attack waves are destroyed, they leave behind cargo and useful items.

The game features simple controls, which can be inverted for left-handed or right-handed play. The controls can also be inverted vertically.
