They Came From Outer Space!

From publisher blurb: Keep Watching the Skies! These Archetypes, Tropes, and other details merely scratch the surface of what you can do with an Outer Space! game. If you maintain the era and setting as laid out in They Came from Beneath the Sea!, you need change very little to make this supplement work for your group. We look forward to seeing your Astronuts and Survivors fighting side by side, all while the Eccentric and Mouth get to argue over who gets to declare “the end of the world is nigh!”
