Fuel Gas Vehicles

Adds fuel gas variants of all unlockable hydrogen vehicles (T2 truck, excavator, large tree harvester, tree planter, amphibious truck and excavator, mega excavator, haul trucks) and a fuel gas station. Each is unlocked by the same research as its hydrogen counterpart.

This Mod includes short excerpts or references to Captain of Industry Game Code. Game Code is © MaFi Games and is used only under the Captain of Industry Modding Policy. No DLC is required.

Fuel gas vehicles use 150% of diesel's fuel and produce 50% of diesel's pollution.

Visuals re-colour the hydrogen vehicles to portray LPG fuel tanks on all vehicles, along with custom icon recolours.

The cargo ship is not included.

Can be added to existing saves, but cannot be removed once fuel gas vehicles or stations have been built.

Known cosmetic quirk: some vanilla vehicles (small excavator, tree harvesters) will list fuel gas amphibious and haul trucks as supported, because vanilla's truck rules check IDs by name and (to my knowledge) can't be modified. Assignment is manual, so this only appears if deliberately assigned.
