POWER UP AND TEST GAME
1. Plug line cord into AC power source and turn on power switch. LEDs in electronics cage should illu-
minate. Use 20-volt DC setting on a digital voltmeter to measure DC voltages at power connector pins. 
Adjust +5V source if is necessary. Voltage tolerances are ±.4 on +5V, ±½ V on +12V.
2. The game begins self diagnostics. If no errors are found, Attract Mode begins. If problems occur, 
check wiring and refer to Troubleshooting Chapter.
3. Unlock and open coin door. Press and hold TEST button to access Menu System. Use tests to verify 
operation of monitor, hard drive, speakers, and all pushbuttons and joysticks.

CREDITS button to allow game play. Choose a player position and press the START button to begin. 
Listen to the audio while playing the game. Note unexpected irregularities in sound (out of phase, no 
low frequencies, etc.). Check the wiring harness for internal shorts. Refer to Wiring for jumper loca-
tions and recommended settings, or Troubleshooting.
5. Close and lock coin door.
6. Play several games to test operation of player panel buttons. Do they function? Do they operate consis-
tently? Does each control perform its designated operation? Game play and earnings depend on proper 
performance of the VIEW, START and movement buttons. If any button does not operate properly, 
check connections against the wiring diagram. Replace intermittent or otherwise faulty controls.

STARTING UP
Each time the game is first turned on or power is restored, it begins executing code out of the boot ROM. 
These self-diagnostic tests automatically verify and report condition of the hardware and the disk drive. 
The screen is blank during these tests. If any of the individual tests fails, then an error message will be dis-
played for each test. The message will be displayed for 30 seconds or until any button is pressed.
• If no buttons are pressed, the system will quickly complete all tests then load and run the game.
 Press and hold the TEST button inside the coin door to skip the boot ROM tests and activate the Self-Test Menu 
System.
Once all Power-up tests have been passed, the game goes into Attract Mode. Scenes and sounds from a 
typical game are alternated with previous high scores in an endless pattern until game play starts.
Insert currency to start game. Play begins after a mission is chosen. The game progresses until time runs 
out. If no more play is required, the game automatically returns to the attract mode.
GAME RULES 
Play instructions are on information panel between speakers. Up to four players at a time can explore a 
world, facing hordes of monsters, searching for treasure, avoiding traps, finding and using magic, and 
adventuring their way to the exits.
Players choose from eight characters (and, later, eight alternate characters) to face the hordes of monsters 
that have overrun the land of Gauntlet. With more than 100 unique monsters and 10 intimidating boss char-
acters, players have their hands full, defeating each of the eight world bosses and collecting keys before 
meeting the demon Skorne. Following Skorne’s defeat, players must defeat him yet again in an underworld 
level, after which they face the evil overlord Garm. Numerous power-up enhancements are scattered 
throughout the land to help players get to the finish.
Players can save their character with player IDs. One password saves all eight different characters. Dur-
ing game variable selection, players simply enter their initials and their own 3-letter player ID that they 
choose. The characters, with their experience levels and current ratings for strength, speed, toughness, and 
magic are automatically saved along with any Rune Stones players find.
To access the alternate characters, players first build characters to level 10. Depending upon which char-
acter they have played, they then can choose to play as the Minotaur (Warrior), Falconess (Valkyrie), 
Jackal (Wizard), Tigress (Archer), Hyena (Jester), Ogre (Dwarf), Medussa (Sorceress), and Unicorn 
(Knight).
To defeat Garm, players must find all 13 Rune Stones and defeat Skorne twice. Three Stones are hidden 
in each world. Upon finding a Stone, a character is saved permanently with a password.
There are over 35 unique special weapons found throughout the game that will help players in their quest. 
These power-ups are found in chests and barrels, in nooks and crannies, and even in plain view and can be 
bought with gold in the Shop.

INDIVIDUAL AND MULTIPLE PLAY
Insert currency to start game. Select a joystick/button combination and press START. Select a password, 
character, and journey. In multi-player games the first to select a journey determines everyone’s path. On-
screen life counters decrease as characters are wounded until they reach zero, at which point the player 
must deposit more coins to continue. You can continue playing after others drop out. When coins are 
inserted, the character joins in the middle of the action.
PLAYER CONTROLS     
START buttons let players begin or continue play and also select items from the service menu.
FIGHT/MAGIC/TURBO Buttons attach enemies. Players access special turbo movies by pressing 
TURBO and FIGHT at the same time when their fight bar has been charged up.
Magic is used by pressing TURBO + MAGIC and FIGHT + MAGIC during game play.
Between levels, players redeem accumulated gold for valuable power-ups and things that will enhance 
their characters like strength, toughness, speed, and magic.
JOYSTICKS advance a character along a journey and select items from service menu.
