From publisher blurb:
Rules light space combat system, Spacestations, Alien Worlds & Creatures for OSR games.
A Colonial Troopers Supplement
The emphasis for Colonial Troopers has always been squad level missions. Eradicating bug hives, smashing pirate dens, taking paid jobs to wipe out a crime boss, or steal a piece of tech from a rogue group. Spaceships were just a way to get from one place to another.
With this supplement the journey can now be the adventure. When you escaped with that weird new weapon from the skinnies that isn’t the end of it. A skinny warship is in hot pursuit, they want their tech back! Ship to ship combat ensues. Blasting their cruiser out of the skies you make fast your escape.
