Subterranean Acquisitions

US TTRPG collective making grimdark adventures since 2019.

We started as old high school friends reconnecting over Saturday night RPGs and grew into a nationwide collaborative creating quality content for the indie gaming community. Every adventure, supplement, and hack we publish is completely free—because great games shouldn't be locked behind paywalls.

Our Philosophy: Make it good. Make it free. Make it accessible.

We focus on grimdark content that we actually want to play at our own tables. From Death in Space adventures to our upcoming Mörk Borg hack Teufelswerk 1690, everything gets extensively playtested and collaboratively crafted across time zones.

No corporate bullshit. No premium tiers. Just quality TTRPG content, free to download and ready to terrorize your players.

For the love of the games.
