From publisher blurb: READY FOR BLASTOFF RIGHT OUT OF THE BOX The Space Hack takes the kickass OSR game The Black Hack and adapts it for science fiction! The Space Hack adds Starship Combat rules to The Black Hack without slowing down its streamlined core, launching the original 1970s fantasy role-playing game INTO THE STATOSPHERE and BEYOND! Choose between three science fiction classes: The Soldier, the Scoundrel, and the Psychic. Fight science fiction monsters and races, such as the Honorable Warrior Alien, Replicants, Sand Worms, Void Lords, Atomic Lizards AND MORE! This is a complete game! The Black Hack is not required, tho I encourage everyone to purchase the excellent parent game. Everything you need to start your science fiction adventure is here, in a ruleset that fits in a single 16-page booklet!
