My personal Mothership favourites. Stuff I've used and loved, or plan to use in my home campaign in some shape or form.
Want more? Here's a big list of Mothership modules, music, tools, supplements, hacks...
_______________________________________________
Vita Nova (Drivethrurpg) - this 24-page module contains guidelines for a cooperative minigame for constructing the players' research base on a dangerous planet that is being terraformed at an unexpectedly rapid pace.
Tombship of the Lich (Terrors from the Cosmos) - I'll potentially reskin this one to fit with either The Gaunt from Dead Planet, or mix it up with The Iron Tomb and The Black Pyramid somehow.
A scientific expedition with the aim to explore and study an ocean planet with a diverse biosphere. An atmospheric module with beautiful art.
20+ hexes with lots of great ideas that are easily taken apart, pillaged, and inserted into various locations in a campaign. Or use it as a hexcrawl campaign in itself.
One of my favorite 1-3 session modules out there, depending on your pacing. Deadly.
