Use class in Jupiter Hell has one or more skills depending on your character’s build, but each class has one ability by default. Each ability uses up resources, and how to refill each resource differs on the class you have chosen. The resource gauge is located below the health in the bottom left-hand corner.

To use the default ability is Right Trigger and Left on the D-Pad on controller and the 5 on keyboard. Remember you need to refill your character’s resource before using the skill again, or it will not happen.


The Marine class resource is called Fury—this is regenerated by killing enemies—and is needed to use the ability Adrenaline, which heals you.

  • Marine
    • Fury
      • For every 30 points of Fury, you may channel your adrenaline to heal a bit. This will also convert one quarter of your main modifier to health and protect yourself from pain for five seconds.
