Grilluminati Lets You Sacrifice Customers, Serve Their Remains and Run a Steakhouse From Hell
Grilluminati launched its free Steam demo on October 19, letting up to four players run a steakhouse that secretly operates as a murderous cult. You'll serve customers, select victims, chop up their bodies, use specific parts for occult rituals and turn the leftovers into ingredients.
I've played the demo solo, and the good news is that this ridiculous criminal operation actually works. The less welcome news is that running a restaurant and a human-sacrifice operation simultaneously turns out to be bloody exhausting.
Apparently, murder is easier than hospitality.

Welcome to Grilluminati, where the customer is always meat
The objective involves completing ten rituals and summoning a god. Quite why a supernatural deity requires a functioning steakhouse remains unclear, but presumably even the forces of darkness need somewhere to take the family on Sundays.
You have regular restaurant responsibilities alongside the cult activities. Customers need feeding, bodies need processing, and rituals demand particular sacrifices. Meanwhile, the furnace requires attention, suspicious behaviour attracts unwanted interest, and the police are apparently incapable of appreciating a small business trying to diversify.
The developers advertise three competing gods, increasingly demanding rituals and supernatural punishment. There's also a system of divine favours, which initially presented me with three rather unusual business opportunities: a broom, donuts or a backdoor.
I went with the speed broom. Obviously.
I have no idea what sort of ancient deity offers cleaning equipment as a blessing, but somebody has clearly looked at the staffing situation and realised we're going to need help.
My first victim presented a minor logistical inconvenience when I discovered that a whole corpse wouldn't fit into the meat grinder. Throwing it around wasn't helping either. It took approximately two seconds to realise I needed to chop the body into smaller pieces.
And there it was. My first lesson in running a successful restaurant: always prepare your ingredients before using the equipment.
Rituals require particular body parts. If the gods demand arms, for example, the remaining anatomy can apparently be put to more commercially productive use. Different combinations produce ingredients for other recipes, adding a rather revolting resource-management element.
I haven't established how profitable those combinations are, but the system is genuinely interesting. Every victim potentially serves several purposes. The question becomes what you sacrifice, what you process and what you retain for the kitchen.
Somewhere, a restaurant accountant is looking at these margins and having a religious experience.
The toilets are the most important room in the building
Playing alone, I quickly realised that murdering customers in the toilets was probably the most sensible approach.
Think about it. Customers voluntarily isolate themselves in a small room, away from the main restaurant. Nobody thinks twice about someone disappearing into the toilet for a few minutes, and even with police wandering around, it seemed a practical place to conduct my unconventional customer-service operation.
I didn't establish whether this reliably prevents detection, but it worked well enough during my opening level. There's something magnificent about operating a cult with supernatural powers and concluding that the most useful thing in the building is the toilet door.
I completed the first level solo without much trouble. You can clearly tell Grilluminati was designed with multiplayer in mind, but playing alone is absolutely possible. It was hectic, certainly, but manageable.
Then level two began.

Apparently, the gods have discovered performance targets
My second level demanded roughly three times as many sacrifices for the objectives I encountered. Divine favours now came with wrath attached, forcing me to consider the disadvantages alongside their benefits.
I actually like that idea. Supernatural assistance should probably involve consequences, particularly when you're dealing with entities whose preferred communication method involves dismembered restaurant customers.
Unfortunately, I spent much of the session feeling rushed.
The furnace needed feeding, customers required attention, sacrifices had to be prepared and ritual requirements kept accumulating. I wanted to explore the systems at my own pace, but the game increasingly felt determined to turn my murderous little steakhouse into a Friday evening shift at a severely understaffed restaurant.
The only real breathing room I remember getting was while waiting for someone to take a dump. A wonderfully peaceful moment. No immediate demands, no frantic running around, just a man enjoying the facilities.
His life expectancy dropped considerably shortly afterwards.
I understand that chaos is a major attraction for people who enjoy frantic cooperative management games. Judging by the early Steam demo reviews, several players absolutely love it.
One reviewer describes organised cooperative sessions degenerating into police pursuits, frantic blood cleanup and meteors falling from the sky. Others praise the ritual rewards, replayability and escalating madness. Another specifically enjoyed both solo and cooperative play, so the pressure clearly isn't universally unwelcome.
For me, though, the concept is fascinating enough that I wanted more time to enjoy it. There's a lovely, grotesque management simulator hiding inside this restaurant, and I'd personally prefer a little breathing room before everything starts demanding immediate attention.
The demo's biggest problem wasn't the police
Unfortunately, my second-level run ended when the final ritual bugged out and prevented further progression. I couldn't complete the objective, so I eventually quit.
That's disappointing because I wanted to discover how later rituals would develop. I can tolerate being defeated by angry gods, suspicious police officers or my own appalling management decisions. Getting stopped by something simply refusing to work is considerably less entertaining.
The first eleven Steam demo reviews supplied during our October 20 check were overwhelmingly positive. However, one negative reviewer reported invisible blood for some players, random crashes and a Windows blue-screen incident. Those are separate reports, not confirmed explanations for the ritual issue I encountered, and the sample is too small to establish how widespread technical problems might be.
I love the premise of Grilluminati. The criminal activities are genuinely playable, with dismemberment, cooking, sacrifices and restaurant management feeding into one another. It's exactly the sort of gloriously deranged villain fantasy that deserves attention.
The cooperative chaos is already winning over early players, and I understand why. Personally, I'd enjoy a slightly calmer version. Give me time to experiment with recipes, optimise my operation and carefully arrange another customer's disappearance without constantly worrying about the bloody furnace.
For now, the free Grilluminati demo is available on Steam.
I just hope the gods eventually learn that a well-run business cannot survive on human sacrifice alone.
It also needs reasonable working conditions.
If sacrificing restaurant customers has awakened an unhealthy interest in being the bad guy, explore CRIMENET's Villain Games hub. Playable monsters, murderous psychopaths and criminal masterminds await. Apparently, saving the world was simply too respectable.
