I'm happy to report that @drivethrurpg.com have added Cairn as a filter (under Old School Revival). Thanks much for that! If you've made something for Cairn, be sure to update the tag there under "Edit Title Listing."
Thanks again everyone.

In 2025 I will begin publishing Cairn supplements for third parties, under the moniker Cairn Press.
If you're a writer and want help with editing, layout, or printing I should be able to hook you up with the right people.
My goal is to make more Cairn content and get people paid for their work.

Brilliant twist 👌
Let's talk items. First up; the flow staff! You can see it in the trailer.
The flow staff folds in to fight and out to fly; both in the game and on the sheet. But it's weaker than most heavy weapons.
All illustrated items have mechanics on the back. Never look up a magic item effect again.

One thing I like about the Junk City adventures is the unique pressure puzzles in each of them. In Puma 242 a swarm of flies are slowly descending down from the roof, while sickening mould is growing up from the basement. Players will have to deal with both threats, but how will they go about it?
PUMA 242. You can download this Mausritter adventure for free. It was written by myself + Isaac Williams and will be part of the JUNK CITY boxset. Just use the link below and search for the big orange button. You can also download the rules for free if you're not familiar with the game!

We talked about the factions much yet! Might as well talk about them here. The factions drive the play in Junk City — each want something from the players, and each put pressure on them from different directions.
@losing.games have the factions in Junk City been described anywhere public yet? i'd love to know what their deals are!
