Gorf [Model 4L 2711]

Gorf © 1982 Bally Midway Mfg. Co.

The object of GORF is to accumulate points by destroying the various types of enemy spacecraft you will encounter as you attempt to complete a variety of space missions.

You begin each game with a fleet of five Fighters. Only one Fighter at a time may fire upon the enemy. The time may fire upon the enemy. The number of Fighters remaining in your fleet is indicated throughout the game at the top of the screen.
Use the joystick to maneuver your Fighter back and forth, and up and down. To fire your laser, press one of the two button trigger buttons on the sides of your controller. You have an unlimited supply of ammunition.
Note: Firing a shot causes a previously discharged bullet to disintegrate if it hasn't yet made contact.

You will be awarded one extra fighter plus a promotion of Rank every time you make it through the series of four space missions.

MISSION 1 - ASTRO BATTLES
Before taking off into space, you must first defend the Earth from the horde of advancing Gorfian Droids. These invaders decscend in column formation and drop dangerous anti-matter bombs. Bonus points are scored for hitting the bouncing Gorf and Command Ship that randomly pass overhead. When the entire attack matrix is destroyed you will proceed on to your next mission. Should any of the invaders bust through your defense shield and reach the Earth's surface before you've destroyed them, this mission will be terminated.

MISSION 2 - LASER ATTACK
This orbital zone is the Gorfian Empire's first line of defense against your counterattack. Destroy the anti-particle Laser Ships while avoiding their deadly beams. Each Laser Ship is protected by three Kamikaze Invaders and a Flying Gorf. They'll continuously try to ram into you as you attempt to blast them all.
Points are scored for all enemies shot and destroyed. No points are scored for Kamikaze Invaders blown up in a suicide-crash. When all attack ships are destroyed, you will move on to your next battle.

MISSION 3 - SPACE WARP
You are getting closer to the enemy Flag Ship! Sensing your presence, it generates an eerie space web which releases Gorfian Attackers and Flying Gorfs firing subquark torpedoes. These aliens are released one at a time and fly in a spiral pattern. When you succeed in getting past this level, you'll be ready for your next and most challenging mission.

MISSION 4 - FLAG SHIP
To destroy the Gorfian Flag Ship and earn the right to work toward your next promotion, you must score a direct hit in the Flag Ship's internal power reactor vent. In order to get a clear shot at this difficult target, you must first blast a hole in the Flag Ship's heavy force field arc, while avoiding the heat-seeking missiles being launched in your direction. The debris that falls from the Flag Ship following a shot to its outer hull is radioactive, but may be fired upon for extra points. Following a successful hit, a violent neutronium explosion will appear in dazzling color as the Flag Ship disintegrates. You are now a Space Captain and will repeat the sequence of missions fighting against progressively faster and nastier robots of the Gorfian Empire!

TWO-PLAYER VERSION
Two players may compete in GORF, alternating turns. Both players must use the same controller. Since only one player can play at a time, sharing should not pose a problem. Just be prepared to pass the controller to the other player when your turn has ended. The screen will notify each player as to whose turn it is.
