Stay Frosty - Space Marine RPG
Battling Bugs, Xenomorphs, or Doom Demons
Takes a lot of cues from the Black Hack, but this is Roll High (low ability scores are good). Also has a tension mechanic, armor reduces damage, procedures for cranking up the danger.
So if Mothership is Alien, this is Aliens.
Ruleset for Slipgate Chokepoint.
GAME OVER, MAN
The bugs are through the perimeter, the gates of hell have opened, the mothership is landing, and the Captain's brain got sucked out...there's only one thing you can do, Marine...Stay Frosty.
Stay Frosty is an OSR game of future marines versus whatever the universe can throw at them. Use these rules to play games in the style of your favorite military sci-fi movies and video games. PC's will have to balance escalating tension and dwindling resources against staying Frosty to complete their missions.
