Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Adventure Mansion is being built around multiplayer moments that are difficult to judge in isolation.

Cocoon Panic begins with four new employees searching an empty attraction for alien pods, but the real fun comes from what players do to each other along the way: splitting up, shouting over walkie-talkies, missing something obvious, panicking, rescuing coworkers, making terrible decisions, and then dealing with the consequences when the pods they failed to destroy begin to hatch.

Early Access gives me the opportunity to build and tune that experience around real groups of players.

The goal isn't simply to make the aliens harder or add more content. It's to make the entire night produce memorable stories.

Searching should be fun with friends.

Finding a pod should create urgency.

Failing to destroy one should matter.

The transition from hunting the infestation to being hunted should feel exciting every time.

And when someone's friend has to slap them back to their senses while another employee is screaming over the radio, that should feel like exactly the kind of disaster the game was built for.

Early Access will help refine the pacing, multiplayer interactions, alien behavior, panic system, level design, difficulty, replayability, and the balance between adventure, comedy, and horror.”

Approximately how long will this game be in Early Access?

“I currently expect Adventure Mansion to remain in Early Access through approximately 2028–2029, although that timeframe may change as the game develops and based on player feedback.

Adventure Mansion is currently developed part-time alongside my development job, so I would rather allow the game to grow at the pace it needs than promise a final release date too early.

The priority is to make the core multiplayer experience genuinely fun first, then expand from a strong foundation.”

How is the full version planned to differ from the Early Access version?

“Early Access will begin with Cocoon Panic as the central Adventure Mansion experience.

Cocoon Panic focuses on new employees alone in the attraction after closing: searching for alien pods, destroying them before they hatch, communicating with a mysterious voice over their walkie-talkies, dealing with panic and other multiplayer disasters, and surviving the dramatic shift that occurs when the infestation gets out of control.

Development will initially concentrate on making that experience as replayable, funny, adventurous, and polished as possible.

Over time, I plan to expand Adventure Mansion itself with additional attraction areas, environmental interactions, costumes, equipment, alien behaviors, secrets, surprises, character interactions, and new ways for situations inside the attraction to unfold.

Adventure Mansion is being designed as a setting capable of supporting more than one kind of strange night, but I don't want to promise specific future experiences before the first one has proven itself.

Cocoon Panic comes first.

The lessons learned from it will help determine where Adventure Mansion goes next.”

What is the current state of the Early Access version?

“Adventure Mansion is currently in active pre-release development, with the immediate focus on completing the first playable version of Cocoon Panic.

The current target is a 1–4 player cooperative experience built around a complete night at Adventure Mansion:

Arrive as new employees → Search the attraction → Find and destroy alien pods → Deal with the consequences of anything you miss → Survive the blackout and active alien threat → Regroup and escape.

Players take the role of Adventure Mansion employees, while the alien threats in the initial version are AI-controlled.

The multiplayer foundation is in place and continues to be refined. Current development is focused on the systems most important to the Cocoon Panic experience: exploring and searching together, destroying pods with Alien-B-Gone, incubation and hatching, alien encounters, panic and coworker recovery, the transition between the two major phases of the round, the mysterious walkie-talkie guidance, multiplayer stability, and Adventure Mansion itself.

Proximity voice chat is implemented as part of the cooperative experience.

The first version is deliberately focused.

Some additional equipment, character abilities, attraction systems, environmental interactions, and other ideas are being held for later so development can concentrate on making the central 1–4 player Cocoon Panic experience fun, readable, stable, and worth replaying with friends.

The game remains a work in progress. Environment content, animation, effects, alien behavior, balance, polish, and the amount of available gameplay will continue to grow throughout development.”

Will the game be priced differently during and after Early Access?

“I expect the price of Adventure Mansion to increase gradually as substantial new content, environments, systems, and polish are added.

Players who join earlier should expect a smaller and less complete Adventure Mansion at a lower price, while later versions are intended to offer a broader and more polished experience.”

How are you planning on involving the Community in your development process?

“Adventure Mansion is a multiplayer game built around the stories groups create when plans fall apart, so watching how real groups play Cocoon Panic will be extremely important.

Feedback will help shape the pacing of the hunt, how dangerous missed pods should become, alien behavior, panic and recovery, attraction layout, difficulty, multiplayer readability, replayability, and the balance between comedy, adventure, and horror.

I am particularly interested in the moments players talk about afterward: the room everyone forgot to search, the friend who disappeared at the worst possible time, the panic rescue that somehow worked, the alien nobody expected, or the terrible decision that turned a manageable shift into complete chaos.

Steam discussions and a dedicated community channel or Discord are planned as places to share feedback as development progresses.

Cocoon Panic will establish the foundation. What players enjoy most about being inside Adventure Mansion will help guide what deserves to grow from there.”

About This Game

WELCOME TO YOUR FIRST NIGHT AT ADVENTURE MANSION

Congratulations.

You and up to three other new hires are the newest performers at Adventure Mansion: a sprawling indoor Halloween adventure attraction filled with creepy mansion halls, strange exhibits, ridiculous costumes, hidden passages, fake monsters, and enough questionable safety decisions to keep management very busy.

Tonight is supposed to be simple.

Learn the attraction. Meet your coworkers. Figure out where everything is before you're expected to perform for actual guests.

There's just one problem.

You're trapped inside after closing.

And something else is in here with you.

Alien pods are incubating throughout the attraction. Search the building, reach the places they're hiding, and destroy as many as you can before time runs out.

Because when the lights go out, anything you missed starts hatching.

Then the hunt turns on you.

FOUR NEW HIRES. ONE VERY STRANGE ORIENTATION.

Cocoon Panic is built around the chaos of four newly hired performers trying to survive an orientation that was only supposed to teach them how Adventure Mansion works.

Learn the halls.

Explore the attractions.

Figure out the employee shortcuts.

Try to remember where everything is.

Then start using all of that information to find alien pods before they hatch.

Easy.

Until a doll starts attacking somebody, a shortcut turns out to be less safe than expected, your coworker disappears into an employee-only corridor, and nobody remembers who was carrying the Alien-B-Gone.

The faster your group covers ground, the better your chances.

The more you split up, the more opportunities you create for everything to go spectacularly wrong.

EXPLORE ADVENTURE MANSION

Adventure Mansion isn't a traditional haunted attraction with one path from entrance to exit.

Its themed Wings are built for exploration, with creepy rooms, side attractions, hidden routes, secret passages, and employee-only corridors running behind the fake mansion walls.

Search each Wing for pods. Follow clues and attraction mechanisms to reach new areas. Unlock backstage shortcuts that let employees move through the building faster than guests ever could.

One minute you may be searching a portrait-filled mansion corridor.

The next you may push through a hidden wall and discover a chain-link service tunnel running behind the scenery.

Adventure Mansion was designed to make visitors explore.

Tonight, that feature has become considerably more important.

HUNT THEM BEFORE THEY HATCH

At the beginning of the round, you are the threat.

The alien pods are hidden.

Your group is searching for them.

Find one and destroy it with Alien-B-Gone before incubation finishes.

Pods may appear inside guest attractions, behind scenery, down hidden passages, or in employee-only areas where they definitely were not supposed to be.

And the infestation isn't helpless.

Alien influence can interfere with Adventure Mansion's attractions, activate hazards, move things that should probably stay still, and create new problems exactly when your group is trying to deal with a pod.

Sometimes the fastest solution is teamwork.

Sometimes it's kicking an aggressive doll across the room.

Every pod you destroy makes what comes next a little easier.

Every pod you miss becomes your problem later.

FAILURE DOESN'T END THE GAME.

IT CHANGES IT.

You aren't racing toward a simple GAME OVER screen.

Eventually, the search ends.

The attraction blacks out.

Surviving pods hatch.

And Adventure Mansion stops being a scavenger hunt.

The pods are gone—and now whatever came out of them are searching for you.

Seek and destroy becomes survive and escape.

Rooms your group confidently searched minutes earlier become dangerous again. Employee shortcuts become escape routes. Dark attractions become places to hide—or places something else may already be hiding.

Regroup with your coworkers, listen for whatever help the mysterious Host can provide, reach the emergency phone, and find a way out of Adventure Mansion while dealing with the consequences of everything you failed to destroy.

The worse your first half goes...

the better the story gets.

PANIC IS CONTAGIOUS.

SO IS THE CURE.

Sometimes a new performer sees a little more extraterrestrial horror than orientation prepared them for.

They panic.

Fortunately, Adventure Mansion has an extremely advanced coworker recovery procedure:

SLAP THEM.

Get close enough to a panicking coworker and smack some sense back into them.

They recover.

You feel useful.

Their mascot head may fly across the room.

Everybody wins.

Probably.

SOME OF THE MONSTERS ARE FAKE

Adventure Mansion was strange long before the aliens arrived.

It's a Halloween adventure attraction built inside a sprawling warehouse: part haunted mansion, part scavenger hunt, part backstage maze, and part collection of attractions management somehow decided belonged under one roof.

Explore mansion corridors, theatrical sets, hidden passages, employee-only spaces, creepy dolls, fake creatures, strange exhibits, and attractions designed to surprise visitors around every corner.

Then experience those same spaces after the lights go out and something very real starts moving through them.

The difficult part is remembering which monsters were supposed to be there.

YOUR HOST IS STILL RUNNING THE ADVENTURE

You're not completely on your own.

A mysterious Host reaches your group through Adventure Mansion's radios and walkie-talkies.

The Host knows the attraction, can track parts of the infestation, tell you which Wings still contain pods, announce when an area is clear, and point your group in the right general direction.

Just don't expect exact answers.

Adventure Mansion was designed around exploration, after all.

If the Host tells you one pod remains somewhere in the West Wing, apparently finding the rest of it is still your responsibility.

Even during an alien emergency.

YOU ARE STILL TECHNICALLY AT ORIENTATION

Adventure Mansion's guests normally explore attractions, solve challenges, discover hidden areas, and collect stamps on their Adventure Cards as they work their way through the building.

You're employees.

You have more important things to worry about.

That won't necessarily stop the attraction from awarding a stamp when you accidentally complete part of the guest experience while searching for alien pods.

And if you happen to get Bingo, the Host will be happy to congratulate you.

Then remind you that you're supposed to be working.

Apparently saving the world does not excuse you from company policy.

DRESS CODE: QUESTIONABLE

Adventure Mansion didn't hire you to carry tactical equipment.

It hired you to perform.

Your group may face the worst orientation imaginable dressed as witches, vampires, frogs, hot dogs, bears, and whatever else management decided belonged inside Adventure Mansion.

Which means every dramatic rescue, desperate escape, and heroic act has the potential to look completely ridiculous.

As it should.

COCOON PANIC

Cocoon Panic is the first Adventure Mansion experience, built around exploration, 1–4 player co-op chaos, changing objectives, and a new hire orientation that gets dramatically worse the longer it lasts.

  • 1–4 Player Online Co-op — Go in alone or bring a full crew of four newly hired performers into Adventure Mansion.

  • Explore Themed Wings — Search mansion halls, side attractions, hidden spaces, and branching routes instead of following a single haunted-house path.

  • Destroy Alien Pods — Find the infestation and hit it with Alien-B-Gone before incubation finishes.

  • Use Employee Shortcuts — Discover backstage corridors and service routes behind the attraction walls to move through Adventure Mansion faster.

  • Listen to the Host — Get updates on pod counts, cleared Wings, and where your group should probably search next. Exact answers are apparently against policy.

  • Deal With the Attraction — Alien interference can activate hazards, affect props, and turn Adventure Mansion's own attractions into additional problems.

  • Create Your Own Disaster — Missed pods don't simply cost points. They survive long enough to change the entire direction of the round.

  • The Hunt Flips — Start by searching for the threat. End up trying to survive what you failed to stop.

  • Panic Together — Keep your coworkers from completely losing it when Adventure Mansion gets a little too real.

  • Slap Your Friends — Adventure Mansion's employee recovery program is unusually hands-on.

  • Ridiculous Costumes, Real Trouble — Horror is much easier to process when the person screaming beside you is dressed as a hot dog.

  • Built for Multiplayer Stories — Split groups, missed rooms, terrible decisions, accidental discoveries, heroic rescues, abandoned coworkers, and desperate escapes are all part of the adventure.

YOUR FIRST ADVENTURE STARTS AFTER CLOSING.

Four new hires.

One empty attraction.

A mysterious Host on the radio.

Alien pods hidden somewhere inside.

And one very important rule:

Find them before they hatch.

Because once the lights go out...

your job description changes.
