What rule set does the game use? I'm looking for some old school sci-fi and this game intrigues me

Thanks

It uses its own rules set, somewhat similar to those of other FGU sci-fi RPGs.

Sorry I'm not familiar with those game systems. Is roll under, over, percentile?

Thanks

Ranged attacks are d20 Roll-under; by range for ships, by attribute for characters.
Many actions are d20 roll-under.
Some are d6+mods roll high (esp. detection rolls, etc...)
Melee is 1d6+STR.

Thanks for that
