Fuel Packs are a vital way to provide energy to power up your different devices in Empyrion. They're quick to manufacture, low cost, and easy to employ to fill your Fuel Tanks and keep your base operating around the clock!
Fuel Packs' Primary Uses
Fuel Packs are added to a multitude of devices, either directly or indirectly. Direct use means that a fuel pack is placed into the devices' Energy Items compartment. Indirect means that you place the fuel pack into a Fuel Tank and then a Power Generator uses the fuel to create power.
Direct Devices currently include: Oxygen Generators and Water Generators.
Indirect Devices currently include: Small Generators, Large Generators, and Generators.
In any case, to use a Fuel Pack, use the default 'T' key to open the device interface when you are looking at a device. (Like an Oxygen Generator). Add Fuel Packs to the Energy Items compartment. For Fuel Tanks, add them to the Container compartment. The devices take care of the rest!
Fuel Packs' Additional Uses
Fuel Packs are also employed as materials for certain recipes. For example, to craft Drill Charges, you need 1 Fuel Pack and 5 metal pieces.
