STEP 1: Make sure that you have unlocked the Goliath race, and one of the supported cars, listed in the IN-GAME SETUP section.
STEP 2: Drive to and enter the Goliath race, then select Solo.
Create a blueprint for a Custom Event with your choice of laps. The more laps that you do, the higher the reward.
The GENERATOR will ONLY run for a single race but you MUST allow the race to finish to earn rewards.
Keep in mind that depending on the speed of your car, a 50 lap race could easily run for several hours.
Turn off Drivatars!
Use an un-tuned / stock car; otherwise it might veer off the road!
STEP 3: Hover over Start Race but DO NOT select it. While HOLDING , HOLD until you feel a heavy rumble to start up the GOLIATH GENERATOR (flashes).
The GENERATOR will automatically change your difficulty settings and start the race.
NOTE: The GENERATOR will run for a single Goliath race and once the race ends, it will shut off automatically after a while. If you wish to cancel the generator early, simply repeat the button presses in Step 3 (Light Rumble). Keep in mind that you WILL NOT receive rewards if you cut the race short!
