POWER TURN-ON

CAUTION - This game must be plugged into a properly grounded outlet to prevent shock hazard and to ensure proper game

operation. DO NOT use a "cheater" plug to defeat the ground pin on the line cord, and DO NOT cut off the ground pin.

WHEN THE GAME IS FIRST TURNED ON it produces a sound. Simultaneously general illumination should come on
and a moment later a scanning “rug pattern”' indicating the RAM test should appear on the screen. Next the rug should
become stationary as the ROM test is performed. In a correctly running game the rug pattern will be followed by the message
"INITIAL CHECKS INDICATE: OPERATIONAL". If RAM or ROM failure messages come up on the screen instead, refer
to Power-Up Tests in TROUBLESHOOTING PROCEDURES.

GAME OPERATION

GAME START - Insert coins; a random sound is produced and credits are displayed on the CRT. With one or more credits

displayed, pressing 1-player start initiates a l-player, *3-turn game. With two or more displayed, pressing 2-player start
initiates a 2-player, *3-turn game.

PLAYER CONTROLS

MOVE JOYSTICK (LEFT) maneuvers mutant clone (our hero) in any of eight directions: N-NE-E-SE-S-SW-W-NW.

FIRE JOYSTICK (RIGHT) fires anti-robot laser gun in same eight directions.

GAME PLAY

ROBOTS ARE THE ENEMY - The player (represented by the mutant clone) must deactivate six types of robots with a laser

gun. However the robots' armada including tanks, electrodes and cruise missiles will be deployed against the mutant.
Meanwhile defenseless normal clones must be protected by the mutant or they will be captured and reprogrammed by the
robots. Arriving at 25,000* points (or any multiple of 25,000), the mutant is awarded a new opportunity to defend his clone­kinsmen.

HIGH SCORE SIGNATURE

Select letters with the MOVE joystick. Push up to move forward through the alphabet; pull down to move backward. Then
push the FIRE joystick up to lock in the letter.

BOOKKEEPING AND EVALUATION TOTALS

1. In Game-Over Mode, open the cashbox and depress the cashbox advance switch. The advance switch located on the

coin door can also be used. The CRT should indicate all bookkeeping and evaluation totals. If so, go to step 3. If the
CRT display comes up in the ROM test, perform step 2.

2. Continue to depress the cashbox advance switch, stepping the game through test programs for ROMs, RAMs, CMOS
RAMs, color RAMs, sounds, switches, and then CRT test patterns, of which there are five. The fifth test pattern, color
bars, directly precedes the CRT display of the bookkeeping and evaluation totals.

3. The bookkeeping and evaluation totals appear on the displays as in Figure 1.

CLEARING BOOKKEKPING TOTALS

1. Depress ADVANCE to display Game Adjustments.

2 Operate MOVE joystick to position cursor on CLEAR BOOKKEEPING TOTALS.

3. Push FIRE.

4. Depress ADVANCE.

GAME ADJUSTMENTS

In the Game-Over Mode open the coin door with AUTO-UP, and depress the coin door ADVANCE switch twice to cause a
CRT display as shown in Figure 2.

To select and then set functions to the desired values, use the MOVE (UP-DOWN) joystick to select the that is to be changed
and then, making sure the coin door is open, use the FIRE (UP-DOWN) joystick to increase or reduce the value of the selected
function.

The number of turns per game can be set anywhere from 1 to 20 (3 recommended). Difficulty is factory-programmed at 5
(moderate; recommended). It can be custom-programmed as desired.

Game pricing is selected with standard settings or with custom settings as shown in Tables 1 & 2. Table 1 lists some common
pricing schemes and directs the reader to the proper entry in Table 2, which shows what the CRT display should look like to
accomplish the desired pricing. Note that free play can be elected by entering the code number 9 at the PRICING
SELECTION function (see Tables 1 and 2).

For standard settings you need change only the PRICING SELECTION. For custom settings, first set PRICING SELECTION
to zero and then set the remaining values according to Table 2.
