If you don't know Mordheim, see https://en.wikipedia.org/wiki/Mordheim
It's a tactical skirmish game in the streets of the cursed city of Mordheim. You built a band and fight against others bands.
The initial game is too tactical but the context is very inspiring.
So, in this hack of Tunnel Goons, I introduce players in this setting.
I hope to complete the game with additional pages explaining the different factions and rules about the corruption of the chaotic magic of the Warhammer universe.
