July 2025
This review is as of 2025-05-12 - Early Access (UPDATE to 7-18-2025 full release at the end.) I've been playing through all the backrooms/poolrooms/liminal space games on steam and elsewhere, and "The Complex: Expedition" ranks pretty high up there. How the game works: * Heavily inspired by kane pixels' short films, you play as a professional surveyor of this strange alternate dimension , using protective equipment, a camera and flashlight. * You explore the nonlinear, large areas of the complex. * You don't interact with anything except light switches and doors. * There are no monsters or combat. * There are a couple very mild jumpscares over about 5 hours of exploring. How I rank this game compared to others: * Great level design, almost as good as that of Anemoiapolis, better than POOLS * Not much interactivity, I wish there was more like in Anemoiapolis or Seclusion * Very chill and relaxing, I adore the sunset pools and mall levels, feels great to just put this game on in the background while you work on something else to relax in the chill vibes. * Great sound and visual qualities, the tape hiss, sound of breathing, cloth movement and footstep sounds are fantastic. An excellent choice for people who like chill, sensory immersive games where exploring is its own reward. UPDATE: 1.0 release, 2025-07-18: Unforunately, while the 1.0 release has slightly better sounds and some more cutscenes, it's actually shorter than the EA version and deletes my favorite pools maps from the EA version. Sad and disappointing for EA fans, but still overall a good game for those who have not tried it yet.

Genuinely probably the most faithful Backrooms experience you can on Steam as of writing, and I doubt anything can really top it. POOLS is another excellent Backrooms based game but I would definitely call that a completely different type of experience compared to this one, and I'm pretty hard pressed to find which one I like more as of this game's 1.0 release because of just how good Expedition was. If you want something that flawlessly captures the essence of what the Backrooms originally was with the initial influx of popularity due to Kane Pixels, this is the game, like I honestly can't recommend anything else. I feel a lot of Backrooms games that come out have forgotten the main thing about what makes the Backrooms so unnerving aside from the unimaginable infra is the ambiance, and I don't mean the general "liminal" vibe of how things look, but the soundscapes, the music, the Complex really goes the extra mile of making you feel lonely in ways extremely few games of similar style have managed to capture. Absolute silence is the most boring way to go about making the Backrooms "scary", and this game does not do that. Without getting into spoilers, The Complex actually got the final sentence of the original Backrooms greentext right. One understandable complaint I've seen from other people/reviewers is that the 1.0 release of the game has for now completely erased the early access version of the game and there's no real way to play that version anymore, which I get why people are annoyed by that, and I do agree it could and should be brought back as a beta branch for those who may have missed out on playing that version, or just wanted to see what's changed, because the older version of this game was very good as well. On the other hand one thing I absolutely don't understand is how people are unironically actually bitching and crying about the $15 dollar price, I don't think even half of these morons even realize the dev literally remade the entire game from the ground up over the past 2 years and actually had the balls to give it out as a free update to everyone who owned the early access version of the game instead of re-releasing a new game entirely. It's pathetic the audacity of you losers to actually complain about the dev asking for $5 more dollars for an extra 2 years of work to new players. Anyone who believes in the $1 dollar 1 hour metric for games is a braindead TikTok drone who should never be taken seriously for anything. tl;dr It's a really good one.

This game gets the backrooms right i.e. spooky liminal feeling which is not just about a bloody monster chasing you. It accomplishes what few games do, being scary without chasing the player. This is about the space and the feeling of being lost and alone. Unique horror experience. 2025 EDIT #2: The remake is excellent, with lots of cool chills up your spine.

This is the best Backrooms game I have ever played. It's a horror game, but it's not on the nose. It's a walking simulator, but it's fun. The environments are barren, but they're interesting. There aren't any chases or screamers, but you're not alone.

If you find yourself wondering if you've been at a place before, it's a 50/50. If you find yourself paranoid about being watched, you're absolutely right.
