Broken Vehicles is a hidden anomaly that you can experience randomly, being first discovered by the A.R.C Team.
If any Vehicle is near or in the Darkroom, it's functioning can cease. It breaks the vehicles engines, making it useless. It can also explode the vehicle into an inferno for 30 seconds.
If any vehicle enters the Big Dark Room it will immediately break, and once again has a chance to explode into an inferno.
