The dungeon is the easy part.
The people in it are not.

Malignus is a colony sim wearing a villain's armor. Read the confirmed systems first, then use the guides to make decisions the game can actually punish you for.

Beginner's guide

A first dungeon that survives its first invasion

The machinery

A colony sim in a dungeon's skin.

The pitch is simple: dig, build, raid, defend. The actual run is a chain of logistics, morale, wiring and timing. These are the four systems that decide whether the hoard stays yours.

Faithful to the source. Honest about the gaps.

The game is in active development. Boss stats, upgrade effects and balance can change before or during Early Access. Every page separates what Mossbomb has published, what official media shows, and what nobody has announced yet.
