The Zorlon Cannon appears on the left side of the playfield, and moves in a direct line with the Yar. This means the Yar is in its line of fire. It is important therefore, to aim the cannon at the Qotile, fire it, and fly out of the way fast!

The Qotile shoots off two weapons: Destroyer Missiles and Swirls. The Destroyer Missiles come in a more or less constant stream, one at a time. The Yar must do his best to dodge them. Periodically, the Qotile transforms into a Swirl. This Swirl winds up and rushes off after the Yar. A Swirl can be destroyed with the Zorlon Cannon by hitting it either at its base location, or in mid-air. As a player's score increases, the Swirl becomes increasingly dangerous.

The glittering path down the center of the screen is the Neutral Zone. This area will protect a Yar from Destroyer Missiles but not from Swirls. While in the Neutral Zone, a Yar cannot fire any energy missiles of his own.

When a Yar is hit by a Destroyer Missile, a Swirl, or his own Zorlon Cannon, he dies. Each player has four Yars (turns) to play in a game. Additional Yars can be earned.

Controls

The Yar will move in whatever direction the Joystick is pushed. The screen "wraps" from top to bottom, bottom to top. This means that if you fly the Yar off the top of the screen, it will appear at the bottom, and vice versa.

The red "fire" button has two separate firing functions: it will fire an energy missile in the direction the Yar is pointed, or operate the Zorlon Cannon when it is on the screen.

The red button is also used to restart turns and games. Press it after each turn to start a new "life", or continue a successful one. Press it at the end of the game if you want to play that same game version again.
