Brightrock Games · Published by Mythwright
Content notice: Clearing out monster carcasses inevitably entails the depiction of: blood, flesh, bones, organs and other types of internal matter. It's also dangerous work, involving: human corpses, hazardous materials, and numerous, often gruesome, ways for the player to meet their end. All scenes of gore are cartoonish in presentation and in-world discussion of death, dismemberment or injury is intentionally comic. Expect crude language, dead clones, and many, many dead Kaiju.
Last updated 10 Oct 2026
Relax and unwind by cleaning up the world’s biggest corpses either solo or co-op. In a Cleaning Sim like no other, your job is to slice up and tidy away Kaiju carcasses, leaving the city clean and serene. Until the next Kaiju attack, obviously.

About the Game
When colossal alien titans run rampant until getting domed by a railgun, the world finds itself in need of a true hero. That’s you: a Kaiju Cleaner who won’t be perturbed by petty concerns like “workplace injury” or “life expectancy”.
After another bastard Kaiju attacks another crowded city, you must use your tools to clean up vast piles of dead monster until the zone is safe for reconstruction. The Kaiju may be dead, but its corpse is leaking radiation, seeping acidic fluids, concealing explosive organs, and generally making the area inhospitable to any other form of life. You’ll probably die as you go about your work, but that’s fine; send another clone, mop up your corpse, and carry on.
When dealing with Kaiju this big, the detritus warrants calling in a team. Up to 4 cleaners can tackle the monstrous mess left behind via online co-op.
Enjoy therapeutic tasks with your own methodology and a selection of helpful tools. Work at your own pace; that giant corpse isn’t going anywhere. Extract and launch Kaiju innards with a meat-wrenching claw, slice them into manageable chunks, slurp up its various jellies, and power-wash detritus until the hazard zone is sparkling clean.
Turn KaijuCorp from a scrappy band of outcasts and delinquents into Earth’s best Kaiju Cleanup firm either solo or as part of a team of up to four reprobates. Complete missions to upgrade your equipment and customize your base, van, and outfit.
Explore environments the Kaiju have rudely died in and figure out what they have against skyscrapers anyway. Pick apart audio logs, chat with your crew, leaf through an evolving codex of Kaiju research, and enjoy rigorous fact-checking with InfoBlast, a legally-recognised news programme.
We think you'll love Kaiju Cleanup if you enjoy...

Small Kaiju?! An insight into miniature madness
Hello Cleaners,Have you been well? That’s great. Us? Not so much.Don’t worry about the game, that’s all going swimmingly. Things are taking shape with exponential levels of polish, quality and gore potential. As developers we continue to thrive, decorating our work stations with potted plants that provoke cherished memories of the world outside. Our mental health metrics are well in-line with accepted game industry standards.No, our issues are with the new Small Kaiju - little rotting things that hitched a ride with their larger cousins before choking on our priceless human air. At first appearance, their corpses are almost…cute. In reality, they are foul. They ooze. They clog our compactors with viscera. The smell is almost indescribable. Frankly, we have to vent and let you know about them because it’s tearing us up inside.Anyway, that’s why we wrote you this letter. Our tea’s gone cold and we’re wondering why we got out of bed at all.INTRODUCING: SMALL KAIJUFor creatures who seem to exist solely to smear fluids across the clean surfaces of our lovingly crafted civilization, Kaiju are deceptively complex. Research suggests that their ecosystem is highly stratified, with diverse species evolving since ancient times to best fulfil specific roles in their multi-faceted ‘society’.The level of advancement witnessed has been terrifying and fascinating in equal measure. Think of Kaiju as the vanguards of their world’s terraforming project - while it’s the certified Big Lads who get the flowers and attract the headlines/rockets, there are legions of unheralded Small Kaiju who take on many of the core functions their bigger counterparts cannot. You’ve got hunters, planters, harvesters, scouts…whether clearing debris or shaping the soil, Small Kaiju are the irreplaceable workhorses of the Kaiju ecosystem. They exist in horrible synergy - until they receive a lethal Earth welcome. Better luck next time!Think of it like how every successful game development team unites speci...Read full article on Community Announcements (armed_joy)AnnouncementsOfficial
InfoBlast! Skegness Supermarket Clusterfluke: UNCOVERED
Hello Cleaners,When we look for methods to cope with our monstrous future, it’s often critical to stare our ugly past dead in the face - and frankly, it doesn’t get much uglier than Skegness 2029.As is so often the case, the transition from beachside beauty spot to radioactive cesspit of intense sadness, was a sudden one. Anchored to the Lincolnshire coast on Britain’s eastern seaboard, Skegness’ population bore witness to one of the Kaiju Crisis’ grimmest incidents, deftly delivered via the finned fury of the Autumnal Slagfish.This moist Kaiju deviant rose from the North Sea to feast upon the local population. Those that survived were faced with radioactive fallout, causing mass devastation, food shortages and grotesque defects - factors that mean Skegness is sadly now only Britain’s second best seaside destination for families.To fill you in on the day the missiles stopped working and the unmitigated crap that followed, we bring you an exclusive listen to our third episode of InfoBlast - salvaged from a dead person’s phone for your entertainment and lore-bothering needs. Until next time, cleaners.- Brightrock Games & MythwrightRead full article on Community Announcements (armed_joy)Community & EventsOfficial
Tools and Tech! Legitimate Cyberpunk Fest Frivolity
Hello Cleaners,Picture the scene. The soft, dull thud of synthetic beats echo down the dark alley, as if synced to the sullen pitter patter of acid rain. There I stand, clad in galvanised duster and neo-cowpoke wide-brimmed hat, shielding my identity from the harsh neon glow of the city lights. My lung capacity bio-mod chirps into life as I inhale a cybernetic cigarette, wearily noting the footsteps of an approaching stranger. It was the Marketing Manager.“I need you to do something for me,” they mutter, voice obscured by a passing aerodyne. “It’s Cyberpunk Fest on Steam. The potential bump in visibility could make numbers go up for Kaiju Cleanup”.I pondered their words as they wirelessly stuffed my holodeck with measly credits. Sure, Kaiju Cleanup has grand & global corporate conspiracy, radical human experimentation, mind uploads, clones, political capture by oligarchy, selective depopulation - all that good stuff. Just look at the tools and tech. But cyberpunk? Really?“I don’t know if the Kaiju Cleanup audience is gonna buy this one, boss,” I say through gritted teeth. “But then…that lot would believe anything”.So we’re doing a cyberpunk-themed blog. And if you don’t like that, you can shove it up your Gibson, ya gonk.Now you’re playing with Kaiju PowerIt’s hard to imagine a world before Kaiju Power. The dawn of the Kaiju Age provoked seismic changes in our everyday lives e.g. how we fuel our homes, light our streets and the increased likelihood of catastrophic brain injury. International collaboration on orbital solar farms felt like a moment of unlikely global unity, until we got one sulphuric whiff of that Kaiju blood and corporation scientists unlocked its staggering power. Now, Kaiju blood boils in our power plants and car engines. Kaiju armour and skeletal remains encase our most efficient batteries. Kaiju-based superconductors are, somehow, a thing. As you next sit gormlessly scrolling on your mobile device, know that such distraction is made possible only...Read full article on Community Announcements (armed_joy)AnnouncementsOfficial
Lore and gore! New Kaiju and Construction Site deep dive
Hello cleaners!It’s Brightrock Games here, the creators of that Kaiju Cleanup game, crafted almost entirely for your betterment. Following last month’s trailer reveal at the Six One indie showcase, you’ve been tongue-wagging and speculating about the contents. This is the kind of front-footed, hard-minded curiosity that makes our audience a cut-above the average consumer. To celebrate, a selection of our coders have been granted one hour of outdoor free play. They thank you.And yet, inevitably, the sun of speculation sets, giving way to the moon of meaning. Your guesses regarding locations and Kaiju lore have been fascinating, illuminating and yet…almost entirely wrong. A shame. So this month, we thought we’d share a glimpse of the truth.Me, you and the Armoured Kaiju - what you need to knowTo the uninformed, this Kaiju appears to don the tell-tale signs of the Coleoptera family (look it up). Wrong. It sports eight grotesque legs to aid burrowing, scaling infrastructure and separating heads from the bodies of an unwitting citizenry.Its dense exoskeleton creates a formidable shield that requires intense periods of exacting laser cutting to reveal the delicious toxic goo within. While this proves to be quite the pain in the arse in death, it’s a far more ultra-deadly inconvenience when alive and nipping.Previous incursions from this foul enemy insect into civilian areas triggered a wave of bombardments from our brave defence forces, but it’s demonstrated itself to be impervious to all typical anti-Kaiju weaponry. Jolly unsporting.The only thing that’s taken this near-impenetrable lummox down has been the development of the ‘Skyrod’ - a modification of kinetic bombardment weaponry that existed long before the ‘Kaiju crisis’ era. These giant spears can be launched from space, navigating the Earth’s atmosphere with guidance fins and thrusters to achieve startlingly accurate trajectories - in this case, directly through this Kaiju’s breastplate (squelch).
