Best ForGroups who want long-form science-fantasy campaigns that move from a ruined Earth to other dimensions. The game suits tables whose GM will decide which parts of the broad setting a campaign uses.Groups who want to play a working-class spaceship crew taking risky jobs on a Western-flavored frontier. It suits tables that like a light core roll, dangerous gunfights, and characters defined as much by their flaws as by their skills.
HighlightsOccupational and racial class packages assign distinct abilities and advancement tracks, giving each archetype a different role in the party. Mega-Damage places many supernatural creatures and war machines on a separate durability scale beyond the reach of ordinary Structural Damage Capacity attacks. Rifts and ley lines make dimensional travel a standing feature of the setting, letting campaigns move between devastated Earth and other worlds.Playing up a mandatory Complication earns Plot Points, so a character's flaws fund the bonus dice and damage reduction they need in a crisis. Plot Points buy GM-approved story facts on a priced scale from inconsequential to major, giving players a measured say in the plot. The crew's ship has its own Attributes, Traits, and Skills, giving its condition and quirks a mechanical role in play.
ConsiderationsCharacter creation combines rolled attributes with extensive skill selection, making first-time preparation lengthy. Combat asks each player to track an action economy, active defenses, and which damage scale applies. Magic and psionics use separate point pools and power procedures, adding class-specific rules to the shared system.Severe Wounds penalize every Attribute die and can require surgery followed by days of recovery. Owning a ship adds monthly bookkeeping: a maintenance roll sets the bill, and each month of skipped upkeep lowers the ship's Vitality toward a breakdown. Social conflict uses ordinary Influence rolls with no dedicated procedure for arguments, negotiation, or deception.
