Fatberg Review

A Janitor's Nightmare Beneath the City Streets

Fatberg commits to one of the least glamorous premises in recent horror-game memory with total sincerity: you're a lowly municipal janitor sent into the sewers to break apart fatbergs — those grim, hardened masses of grease, wipes, and waste that clog real-world sewer systems — before an incoming rainstorm turns the job into a citywide emergency. Naturally, something considerably worse than sewage is living down there, and what starts as an unglamorous maintenance shift turns into a first-person survival horror crawl through Lovecraftian-tinged tunnels, armed with a shovel, a nailgun, and an aerosol flamethrower against creatures that very much do not want to be disturbed. It's a deliberately unpretty setting rendered in a committed PS1-era visual style — chunky polygons, murky texture work, that specific grainy dread the format is known for — and reviewers consistently single out the sound design and atmosphere as the game's strongest asset: "The sound design is excellent; good music similar to 70's-80's horror, satisfying sound effects... for some reason the sound breaking the fatbergs is really satisfying," one reviewer wrote.

Released September 1st at $9.99, Fatberg landed to a genuinely split reception: 4 of 8 English-language reviews positive, and 7 of 12 across all languages. That's a meaningfully more contested response than most of the other 2026 releases in this cycle, and the pool makes clear exactly where the disagreement lies.

Atmosphere That Outpaces Its Own Pacing

The praise and the criticism in Fatberg's review pool both circle the same core issue from opposite directions: this is a slow, deliberate game, and reviewers are split on whether that deliberateness serves the horror or just wastes the player's time. On the positive side, more than one reviewer credited the unhurried pace with genuinely building dread rather than rushing toward jump scares — "a very, very strange game with amazing atmosphere and tense gameplay," as one put it. On the negative side, the complaints are pointed and specific. "You walk at a pace that i could describe as 'old lady with a hip replacement and a walker speed,'" wrote one reviewer, adding that the game's frequent backtracking sections turn short distances into what feels like a mile covered at that crawl. Multiple reviewers independently asked for a run or sprint option that simply doesn't exist, describing themselves reflexively pressing a sprint key that does nothing.

That pacing complaint compounds with a structural one: several reviewers noted that each new area introduces its own small pool of one or two enemy types and rarely builds on them meaningfully, leaving large stretches of hallway with nothing to do but walk. "There's a lot of padding... a lot of hallways with no purpose other than to be long and take up your time. No details, just an empty hallway," read one particularly frustrated review, which otherwise praised the game's visual polish and early level design. Another reviewer put a number on it, estimating the game runs roughly three times longer than its content actually supports, and described repeatedly dozing off during extended walking stretches through empty corridors.

A Weapon Loadout That Mostly Works

Where Fatberg fares better is in its actual combat, limited as it is. The shovel — ostensibly the most basic melee option — draws surprising praise as the most consistently useful tool in the loadout, while the aerosol flamethrower gets called out by name as a weapon that will more likely get its wielder killed than save them. One reviewer offered a useful point of comparison for anyone familiar with the wider "gross-out survival horror" subgenre, noting that Fatberg plays "much more like a proper first-person shooter" than the more shooting-light cleaning-sim hybrid of games like Revenge of the Colon, while conceding that Fatberg's own narrative is comparatively thin — reduced, in their words, to little more than "the sewer is ****ed; get down there and clean up the fatbergs or you're fired." For players coming to the genre specifically for combat variety over story depth, that trade-off may land better than it did for reviewers hoping for a richer plot.

A Developer Listening Fast, If Not Fixing the Core Issue

Lilou Studio's launch-week track record shows a team paying close attention: a small "Small Fixes" patch landed the day after release, following a marketing cadence that had already run for roughly nine months prior, from a December 2025 announcement through a January 2026 public demo and an August trailer confirming the release date. That's a studio that clearly wanted to give the game a proper runway rather than rushing it out the door, and it shows in the parts of Fatberg that work — the sound design, the visual identity, and the general polish reviewers praise even when they're criticizing the pacing. What's notably absent from that early patch, though, is any indication of a movement-speed adjustment or an added sprint option, the single most frequently requested change across the review pool. Whether that's a deliberate design choice the studio intends to stand behind or simply not yet prioritized this early into the post-launch window isn't clear from the available patch notes, but it's the one change most likely to resolve the sharpest disagreement in Fatberg's reception.

Verdict

Fatberg is a game of two very different reads depending on how much patience a player brings to it. The atmosphere, sound design, and committed PS1-horror visual identity are all genuinely well executed, and the premise — mundane municipal labor turning into cosmic-horror survival — is inventive enough to stand out in a crowded retro-horror field. But the absence of any way to move faster than a crawl, combined with backtracking-heavy level design and thin enemy variety stretched well past its natural length, turns what should be a tight two-hour horror experience into something several reviewers describe as an active slog by the halfway point. At $9.99, this is a reasonable pickup for genre fans who specifically want atmosphere over pace and don't mind a slow walk through the muck — but it's an easy one to bounce off if pacing patience runs thin, and the review pool's even split reflects exactly that divide.
