Core Mechanic

Roll d100 at or below the relevant skill percentage to succeed. Difficulty changes the target percentage. Opposed tests compare success levels and then the highest successful roll.

Best For

Groups who want to build a spacefaring campaign around a shared ship and conflicts between alien societies.

Highlights

Modular ship construction connects crew space and equipment choices to handling and damage in combat. Extended Conflicts use depleting pools to make withdrawal a meaningful choice during negotiations and chases. Passions turn personal loyalties into skill bonuses and conflicts between competing commitments.

Considerations

The group must supply its campaign setting and adventures. Standard combat tracks injuries by body location and can leave permanent damage. Depleted conflict pools can impose skill penalties that persist into later scenes.
