Rimworld

After a chance encounter with Dragoons and Traders turns a routine planet exploration into a rout that kills his team and his career, Lieutenant Ethan Fargo, medically retired, wants nothing more than to hole up in the backwater Rimworld he’d explored and enjoy a quiet retirement far from people or problems.

Tight Bridge Technologies hired Ethan Fargo and his militia to guard their power stations on the planet Endine against mob unrest and sabotage. When they arrive, they find the planetary authorities don't want outsiders around to uncover their dirty secrets, and the Galactic Patrol's not interested in providing backup. They all but order him to stop making waves, kicking asses, and taking names. 

Danny Ortega was a failure. He couldn't tolerate the implant to be a starship captain. But Danny Ortega has run his deep-space research vessel Ghost alone for years, flaky AI and all, mapping the most unstable and unexplored regions of the Rift for the Cartographers Guild. When his latest mission lands in a mass graveyard of ships, including some ships out of legend, lost for hundreds of years, the guild isn't happy with him. He picks up a misfit crew out of the asteroids, and the games begin!
