REA Reaction

I’ll admit that I was nervous going into Slaughterhouse, but maybe not for the reasons you’d expect.

The intensity of horror is always relative to an individual’s specific fears, and as a lifelong vegetarian, I’m terrified of meat. I’ve had nightmares about childhood bullies trying to trick me into eating meat, and I’ll still avert my eyes walking through the meat aisle in the grocery store. When it comes to escape rooms, I can get by with gore, darkness, or being chased by a monster, yet a meat locker filled with animal corpses disproportionately freaks me out.

Given that, I was surprised by just how much I enjoyed Slaughterhouse. While this experience was undoubtedly scary — with a murderous menace actively after us and a fairly gruesome environment — Slaughterhouse was much more than just jump scares. I was particularly impressed by the ways in which One Hour had managed to design some creative puzzles that required layered environmental observation, not skimping on gameplay quality while still maintaining an appropriate difficulty level for a horror experience.

While there wasn’t much to the story of Slaughterhouse beyond “avoid getting slaughtered by the big bad guy,” there was a ton of personality in the details. The butcher’s creations were sculptural and at times almost fantastical. As our captor toyed with us, bits of humor seeped into the environment and some of the gameplay itself.

When Slaughterhouse first opened in 2019, it cracked the TERPECA top 50, and it was one of the first games that started to put Paris on the map for escape rooms. While the Paris market has exploded with even more ambitious premium offerings in the past couple of years especially, Slaughterhouse impressively still held up for its age. The game has been well maintained, and at the time of our visit, One Hour was in the middle of installing a new puzzle to upgrade the ending sequence. For puzzlers who dislike horror, Slaughterhouse is certainly not the game for you. But for horror fans who also like puzzles, Slaughterhouse has a lot to offer.

Who is this for?

• Horror fans

Story

Some urban exploration of an abandoned slaughterhouse quickly took a turn for the worse as we found ourselves targeted by a murderous butcher.

Setting

Slaughterhouse took place in a gruesome, abandoned slaughterhouse. It was filled with body parts, equipment for killing and processing various creatures, and plenty of chains and bars to ensure nothing — and nobody — could escape.

Gameplay

One Hour Escape Game’s Slaughterhouse was a horror escape room with a moderate level of difficulty.

Core gameplay revolved around solving puzzles, communicating, and avoiding being slaughtered.

Analysis

➕ For an actively scary game, Slaughterhouse also included some interesting puzzles. The gameplay was not overly difficult — it was still appropriate for an experience meant to keep players constantly on edge — yet it prompted more ahas than usual for the horror genre.

➖ The opening act was weaker than what followed. It was challenging to parse a low-contrast drawing, especially in low lighting. Loud music made it difficult to communicate between spaces. While this scene was fitting for the slasher genre, it felt more generic than One Hour’s interpretation of the rest of the space.

➕/➖ The lighting overall revealed just enough, guiding us through the space and offering flashes of what was ahead. In other cases, it was difficult to see a few key details, and we couldn’t always trust whether we should stay out of pitch darkness.

➕ Without a shadow of a doubt, Slaughterhouse created some unexpectedly beautiful scenes within its gruesome and detailed environment.

➕ Slaughterhouse also featured moments of quirky humor, both in the story and the gameplay, that offset the grim intensity while still fitting within the same world.

➕/➖ A solo interaction conveyed a lot in a small space, yet there was an opportunity to escalate the intensity of the gameplay here to better take advantage of a unique and highly thematic feature.

➕/➖ The menace was effective in building tension and keeping us on edge throughout. However, I questioned the safety of a couple of jump scares in enclosed or uneven environments, particularly when it wasn’t always clear whether we were meant to freeze or rapidly retreat.

➖ A late-game interaction required recalling a small detail that was truly a shot in the dark if players hadn’t noticed it earlier in the game. Some additional signposting would go a long way in maintaining momentum through this segment.

➖ Two pieces of safety equipment were used as part of the gameplay. While it was abundantly clear in context that these items were part of the gameplay, this sets a questionable precedent for players’ trust in safety measures in other escape rooms.
