What the developers have to say:

Why Early Access?

“Adventure Mansion is being built around the kind of multiplayer moments you can't always plan for.

Cocoon Panic starts with a simple job: find the alien cocoons before they hatch. What makes it fun is everything that goes wrong along the way—lost coworkers, bad decisions, unexpected scares, and the occasional desperate rescue.

Early Access will let me develop and refine those experiences with actual groups of players, improving the pacing, alien behavior, panic mechanics, exploration, and overall multiplayer chaos.

The goal isn't just to make a bigger attraction. It's to make Adventure Mansion somewhere players want to return to with their friends, even when they know everything is probably going to go wrong.”

Approximately how long will this game be in Early Access?

“I currently expect Adventure Mansion to remain in Early Access until approximately 2028–2029, although that timeframe may change based on development and player feedback.

I'm developing the game part-time, so I'd rather give Adventure Mansion the time it needs than rush toward an arbitrary release date.

The priority is making Cocoon Panic a genuinely fun, replayable multiplayer experience before expanding further.”

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

“Early Access will focus on Cocoon Panic, the first Adventure Mansion experience: a 1–4 player cooperative adventure about four new employees trying to stop an alien infestation inside a sprawling Halloween attraction.

Development will focus on expanding and improving that experience, including the attraction itself, alien encounters, player interactions, atmosphere, replayability, and the ridiculous situations that make playing with friends entertaining.

Adventure Mansion is intended to become more than a single adventure, with room for new areas, surprises, and potentially additional experiences.

But those are possibilities, not promises.

Cocoon Panic comes first. Where the attraction goes afterward will depend on development and what players enjoy most.”

What is the current state of the Early Access version?

“Adventure Mansion is currently in active development, with the immediate focus on completing Cocoon Panic.

The initial goal is a focused 1–4 player cooperative experience where players explore Adventure Mansion as newly hired performers, search for hidden alien cocoons, and try to destroy them before they hatch.

What happens when the team fails to contain the infestation is just as important as the hunt itself.

The first version is being designed around that complete gameplay loop, with AI-controlled alien threats, cooperative exploration, panic, player interactions, and the transition from hunting to survival.

The multiplayer foundation is in place, and development continues on gameplay systems, animations, alien behavior, the attraction's environments, and overall stability.

Additional ideas are being saved for later so the initial experience can be polished, understandable, and enjoyable with friends.”

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?

“The best moments in multiplayer games are often the ones nobody expected.

I want to see what happens when real groups enter Adventure Mansion, where they go, what surprises them, what makes them laugh, and what makes them want to play another round.

Player feedback will help shape Cocoon Panic's pacing, difficulty, alien behavior, exploration, and overall balance between adventure, comedy, and horror.

Steam Discussions will provide a place for feedback, ideas, and development updates, with additional community options planned as development progresses.

The long-term goal is to build an attraction players enjoy exploring, with plenty of reasons to keep coming back.”

About This Game

WELCOME TO ADVENTURE MANSION

You and up to three others. Friends? Randos? People you barely tolerate? Doesn't matter. Tonight, you're coworkers.

Congratulations! You've been hired as performers at Adventure Mansion, a sprawling indoor Halloween attraction packed with creepy rooms, bizarre exhibits, ridiculous costumes, hidden passages, interactive attractions, and questionable safety standards.

Your first assignment? New-hire orientation. Your second? Surviving it.

Explore strange attractions, get scared, and try not to panic. And when a coworker completely loses it? Give them a good slap to snap them back to their senses. Yes, really. Management calls it teamwork.

Your official new-hire orientation photo. Management has high hopes.

AN ADVENTURE BUILT FOR CHAOS

Adventure Mansion is a 1–4 player co-op horror-comedy where exploring is half the fun and surviving your coworkers might be the other half.

Discover hidden passages, explore bizarre attractions, encounter unexpected scares, and get into situations that probably weren't covered during orientation.

Stick together or wander off. Take the obvious route or see where that suspicious passage leads. Push the button you're clearly not supposed to push.

One person finds something terrifying. Another is definitely somewhere they shouldn't be. Someone says they've got everything under control.

They don't.

The attraction was designed to be an adventure. Nobody said it would be a safe one.

FIRST UP: COCOON PANIC

Your first orientation has taken an unexpected turn.

Alien cocoons are hidden throughout Adventure Mansion, and they're getting ready to hatch.

Your job is simple.

Explore the attraction. Find the cocoons. Destroy them before time runs out.

Easy, right?

Unfortunately, creepy dolls, unpredictable attractions, and panicking coworkers have a way of turning simple jobs into complete disasters.

And anything you miss gets to hatch.

When the lights go out, the things you were hunting start hunting you.

YOUR ADVENTURE STARTS HERE

Cocoon Panic is just the beginning of what Adventure Mansion is being built to become: a playground of strange attractions, unexpected challenges, exploration, and ridiculous multiplayer adventures.

Different adventures. Different disasters. The same questionable management.

Some of the monsters are fake. Some of the scares are intentional.

The rest? Management is still looking into that.

Wishlist Adventure Mansion. Your orientation is going to be a disaster.
