About This Demo

The demo allows you to play 4 rituals. It has partial controller and Steamdeck support.

--

In Grilluminati, up to 4 cultists must serve one of 3 rivalling gods through bloodshed, worship, and increasingly demanding rituals with increasingly disturbing ingredients. Every shift is a co-op cult operation.

The Offerings Must Be Made

Scout the room, isolate your next victim, and take what your god demands before anyone notices. Some rituals require specific body parts. Others demand a full human sacrifice. Dispose of what remains... or put it back on the menu.

Hide the Evidence

Guests notice missing people, blood trails, strange behavior, and whatever your least competent cultist just dragged through the dining room. Keep the room calm, finish the ritual, and make sure nobody catches you in the act.

Perform Dark Rituals

Unlock new powers and tools to harvest the “right” ingredients. Execute rituals together under pressure and push your luck for greater rewards. But beware... when you fail, your god may choose an offering from your own cult instead.

Summon Your God

Choose the god you want to bring into this world. Each god changes the challenges, rewards, and risks your team faces. Rival gods can interfere mid-shift, creating sudden disruptions that force your team to adapt.
