Daemon Engine

A daemon engine is, as the name suggests, a machine which has been constructed/fused with a daemonic entity, resulting in the combination of the two into a living mechanical creature that often is all but unstoppable.

Daemon engines can be found in many shapes and forms in a number of RPGs and miniature games, often representing some of the greatest horrors in those settings.

Warhammer 40,000

In Warhammer 40,000, the first daemon engines were "Possessed Vehicles" which were controlled by daemons. This gave them a resilience to certain damage results (e.g. "crew shaken", as there was no crew to be shaken), at the cost of reduced BS (as daemons aren't great shots) and, for transports, a chance to eat a passenger.

The first "proper" daemon engine is the Defiler though, a giant six leg crab/spider walker with a big cannon, claws and an intense amount of terror added. After that a few years later more daemon engines would be popping up in the later edition of the Chaos Space Marine codex and now you can field armies of these monsters with your chaos marines, a host of clanking, oil and blood leaking horrors.

Warhammer Fantasy Battle

In Warhammer Fantasy Battle, the Chaos Dwarfs, always such cheery fellows, decided to get in on the action and create their own hell cannon, which is powered by feeding people into the maw of the cannon which then fires their spiritual remains as powerful barrages. For a while the chaos dwarfs that came with the cannon as crew were the only official ones made by Games Workshop. Thankfully, Forge World have now made a whole load of chaos dwarfs models so you field an army of the tusky psychos and whats more they have a whole host of daemon engines now, including a daemon train powered by death to pull all of your engines into battle. All hail the rape train of dwarfy death!
