Six-Gun Doomsday schedule and playtesting opportunities
6 months ago – Sat, Nov 29, 2025 at 08:59:40 AM

Hi all; we'd estimated the book delivery would be at the end of January 2026. I'm sorry to say it'll be a bit later than that. We''re aiming for shortly after that and will keep you updated when dates firm up. 

Meanwhile if you'd like to play in one of our playtests of the game we're running them online in December. You just need to join our Discord server:

Nov Update - Six-Gun Doomsday
7 months ago – Sat, Nov 08, 2025 at 06:38:04 PM

Hi all, sorry for the radio silence, we've been nose down on the Six-Gun Doomsday work!
The rules, setting etc are in editing now, and looking great. If you were an early playtester there's been a lot of cool changes!
  • Four character Types: Believers, Searchers, Tinkerers and Defenders.
  • Tons of new Descriptors
  • More new Foci
  • wacky creatures
  • Cyphers are one time abilities, in alignment with "subtle" cyphers from the Cypher System Revised rulebook.
  • Mechanical cool stuff are Artifacts, usually with a limited number of uses, but you could always tinker with them...
  • Character damage: characters start with 6 levels in their Life Pool, and damage removes a level (or more!).
  • Death options: at zero life levels, you can choose to "Go For Broke" (flipping a coin and either dying permanently or being alive again with 4 Life levels,
    or go "Aces and Eights", making a deal with the spirits, gaining 4 Life levels, but perhaps chancing later repurcussions...
    NEXT STEPS
    Finish the artwork, finish the complete adventure (there's been a ton of cool things added!) and final layout. 

    We'll be finished Spring of 2026, as early as possible. 

Catch us at upcoming Conventions! We'll be at PAGE (Philly Area Gaming Expo), TotalCon and Rising Phoenix.
