I have updated my Solo and Campaign rules for Warhammer Underworlds to version 1.4. Titled: Detailed Lore, this version adds every warbands’ lore. It also adds a lot of new rules for when playing solo against the AI. Plus many more changes.
I have updated the roster sheets for Underworlds and Arena Mortis campaigns. They now have more detailed box spaces. Finally, I have added a new warband for Season 5: Harrowdeep.
Read the current version 1.4 rules here: Warhammer Underworlds: Solo and Campaign Rules.
Highlights:
- Added lore for all available warbands.
- Added eight or more AI rules.
- Changed Campaign Roster and Arena Mortis Sheet for easier campaign tracking.
- Added Blackpowder’s Buccaneers warband.
- Various minor fixes and changes.

These rules look very interesting! I will give them a try once my box arrives. :)
Let me know how it goes if you do.
