The universe of Munchkin Warhammer 40,000 continues expanding with the newest supplement, Cults and Cogs. The weird Genestealer Cults infiltrate worlds by manipulating DNA . . . by the time you realize they’re among you, it’s already too late. The metal-and-machine clad Adeptus Mechanicus are more direct, sending in warriors wearing mechanized armor to lay waste to the world.
The Gutbuster Mawtribe are obese, gluttonous, bloodthirsty ogors whose hunger for combat burns as hot as their hunger for everything else. The Ossiarch Bonereapers are highly disciplined troops loyal to Nagash. You can serve them in life or serve them in death - they aren't picky.
The life of a Munchkin is pretty simple: kick the door open, beat up the monster, take the loot, gain levels, and get famous. Just watch out for the other Munchkins looking to also get that loot. There’s no honor among Munchkins, and they’ll gladly stab you in the back.
You’re a Munchkin. You don’t do anything halfway. Sure, you could just go straight down to the bottom of the dungeon and fight the boss, but you’d be missing out on all the extra cool stuff to find. Where’s the fun in that? Why not take a trek off to the side and see what lurks there?
