Classroom 3B Demo

The Classroom 3B Demo Arrives September 10

The Classroom 3B playable demo will be available on September 10, 2026.

Since the first version of the game was shown, Classroom 3B has continued to grow. The demo has been expanded to give players a much better look at the paranormal investigation gameplay planned for the full game.

Paranormal Equipment

The demo now introduces multiple pieces of investigation equipment that players can carry and use while exploring the school, including:

• EMF Reader — detect areas of unusual electromagnetic activity.

• Thermometer — search for abnormal temperature changes and cold zones.

• UV Light — reveal evidence that cannot be seen normally.

• Night Vision — investigate dark areas when ordinary visibility isn't enough.

• Flashlight — your standard light source while exploring the abandoned school.

These tools are not simply being added as collectibles. They are the beginning of a larger paranormal investigation system being developed for Classroom 3B.

What This Means for the Full Game

The September 10 demo is only an introduction.

For the full release, I plan to expand the school, investigation mechanics, paranormal equipment and evidence systems significantly. Different areas will contain unusual EMF activity, temperature changes and other paranormal signs that players will need to investigate using the correct equipment.

The full game is also planned to feature more investigation tools, additional puzzles, more evidence to discover, expanded areas of the school, and a more active supernatural threat as the investigation progresses.

The goal is to make exploring the school feel like an actual paranormal investigation rather than simply searching rooms for scripted clues.

Play the demo September 10, 2026.

Development Progress Update #1.

New Screenshots, Gameplay Trailer & Demo Update

I’ve updated the Classroom 3B Steam page with new gameplay screenshots showing more of the atmosphere, paranormal investigation equipment, night vision, and the direction I’m taking the game.

Demo Update

The Classroom 3B Demo is currently in the review/testing process.

I’m allowing roughly two weeks before making the demo public, as I want to make sure the version you play is stable and properly represents the direction of the game.

I also want to clarify what you should expect from the demo.

The demo is not the full game.

It is a short vertical slice designed to introduce the school, atmosphere, investigation mechanics, paranormal equipment, and give you an idea of how the story will unfold.

It will not contain the complete story, every puzzle, every location, or every mechanic planned for the full release.

The current demo includes 4 paranormal investigation tools. For the full game, I’m currently planning around 10 different pieces of equipment, along with a much more developed inventory and equipment purchasing/progression system.

The environments, investigation mechanics, puzzles, paranormal events and overall horror experience will also continue to expand beyond what you see in the demo.

About the Ghost

I’ve also seen the feedback regarding the current ghost, particularly comments that its appearance isn't scary or polished enough.

I agree that it needs more work.

The ghost currently shown is still an experimental/work-in-progress implementation, and I’m actively working on improving its appearance, behaviour and overall presence.

The version you encounter in the final game will not simply be the demo ghost left unchanged. My goal is to deliver a significantly stronger and more frightening paranormal experience in the full release.

A Note From Me

Classroom 3B is being developed by me as a solo developer.

Building the environment, gameplay systems, equipment, story, puzzles, horror events, optimization and everything surrounding the release takes time when one person is handling the project.

That is also why I sometimes choose to delay something rather than release it before I believe it is ready.

The demo is a preview of the direction I'm taking Classroom 3B — not the finished vision of the game.

I’m reading the feedback, improving what isn't working, and continuing to build on what is.

Thank you to everyone following the development of Classroom 3B.

CLASSROOM 3B IS COMING TO STEAM NEXT FEST

Classroom 3B will officially be participating in Steam Next Fest — October 2026.

This will be an important opportunity to put the game in front of a much larger Steam audience and let players experience Classroom 3B for themselves through the demo.

Over the past few weeks, I’ve been focused on improving the demo, refining the atmosphere, fixing issues, and making sure the experience represents the direction I want to take with the full game.

There is still a lot more planned beyond the demo, and your feedback during Next Fest will help shape what comes next.

About This Game

Classroom 3B

Something happened here. The school was never reopened.

Classroom 3B is a first-person psychological horror game set inside an abandoned Indian school — built from real locations, real details, and a mystery that was buried for a reason. Restore power through a failing fusebox system, monitor seven CCTV feeds for signs you're not alone, and piece together what happened using documents, audio logs, and evidence hidden throughout the building.

The deeper you dig, the less the school lets you leave.

Features
.Explore a fully realized abandoned Indian school — rain-soaked corridors, flickering fluorescents, and details that feel .unsettlingly familiar.
. Manage a fusebox-driven power system that controls what you can see — and what sees you.
. Monitor 7 live CCTV feeds from a single security room — and learn what happens when one goes quiet.
. Investigate using documents, audio logs, and physical evidence to reconstruct a tragedy the school tried to erase.
. Face escalating paranormal events — from peripheral glimpses and audio-only dread to full-blown horror set pieces at key story beats.
. Experience authentic Hindi voice work and environmental audio built specifically around Indian horror atmosphere.
. A tense, combat-free single-player experience — this is about investigation and fear, not fighting back.
