Promethium Tanks Refuelling...
In the ash wastes of Necromunda, fuel is as vital as water. Becoming stranded in the weather-blasted expanses leaves a vehicle exposed to the elements and the attention of roaming gangs. Those with access to a supply of promethium are rich in credits, ammo, and the ability to freely traverse the ash wastes. As a result, fights around refuelling stations are commonplace, with many gangers having met their end at the hands of rivals desperate for promethium, or blown to pieces when a stray shot pierced a tank of the volatile fuel.
