About This Game

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.

Features

  • One Cult, Four Conspirators: Work together or blame each other when everything spirals out of control

  • Hide a Cult in Plain Sight: Perform dark rituals while maintaining the illusion of a grill restaurant

  • Stealth, Suspicion & Escalation: Customers react, panic spreads, and small mistakes become disasters

  • Perform Disturbing Rituals: Harvest bizarre ingredients and unlock new powers, tools, and horrors

  • Rival Gods & Consequences: Choose your deity, each with unique challenges, rewards, and punishments

Mature Content Description

The developers describe the content like this:

This game contains stylized depictions of violence and dark humor. Players take on the role of cult members who isolate and kill customers as part of ritual sacrifices. Bodies may be dismembered or processed into “ingredients,” and players may need to clean up blood or other evidence.

Violence is presented in a non-realistic, cartoon-like style and is often framed in an absurd or comedic tone. The game may also include themes of cult activity, ritual sacrifice, and occasional betrayal between players (such as sacrificing a teammate as part of a ritual).

There is no depiction of sexual acts or sexual violence.
