Fuel

Fuel is a necessary material to be able to go on expeditions to the Planets with your fleet, this must be acquired prior to the expedition.

The cost of fuel will vary depending on the Planet you wish to explore, the farther away the Planet is, the more fuel will be needed by your fleet to go explore it, the approximate value of fuel is 10% of the reward of that Planet.

All fuel costs are calculated with the Planet's base rewards, meaning, fuel cost will not increase as you level up.
