May 2025
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: Based on recent trailers for the new version of the game, this review will probably be dated. I hope it won't be.

This review is as of 2025-05-12 - Early Access 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.

I took some shrooms and played through this game and... wow. This game is absolutely beautiful. Every inch of liminal space was just perfect. It scratches your brain in such a nice way. What I love about this game is that there really aren't any entities (other backrooms games get kind of cringe with it), so this was truly refreshing. The scariest aspect of this game is the ambience. The dead silence. The design. The radio music. The liminal spaces themselves. Everything was just so insanely put together. I will say, the tall figure that makes a few appearances was SO SCARY ON SHROOMS (so. so. so. scary) but it was still great. This is one of those games you have to play multiple times to fully experience all that it has to offer. 11/10 would play this on shrooms again

the game is probably one of the best takes on the concept of backrooms, considering how the other backrooms games just throw out some stupid *ss entities to try to make the gameplay "interesting". well, there are some encounters in this game too, which I'm not going to spoil, but this game does not need entities that are constantly chasing you and trying to kill you at all times. this game has its own way of implementing thrill by just its atmosphere and setting alone. so I'd say this game is conceptually outperform the other titles of the genre with that being said, I'm in no way stating that this game is perfect. the flashlight is automatic and it turns on in dark areas but sometimes it doesn't, so you have to basically just listen to your footsteps and guess if you're actually going in a certain direction or stuck walking towards a wall - as stupid as that sounds... during some parts of the levels that you have to crouch through narrow spaces, it feels like it's impossible to get the right angle to pass through and for the character to actually squeeze out of there... so at times, you may have to press the crouch key a couple of times, walk back, take a break and then try to pass through again etc. overall though, give this a try if you like the backrooms genre. it's definitely a decent experience and there's a good amount of interesting levels to see. it's a short, 1-2 hour game that will stress you out a lot, maybe even more than you think

This is what backroom games are meant to be. No chase sequences, no hiding in lockers, no cheap jumpscares, no survival mechanics, just a walking simulator through strange liminal rooms and hallways.
