An atmospheric horror, exploration and automation game all set in the dim halls of an apartment building
You live in a dimly lit, exotic apartment basement in a small, cluttered office. You don’t know what your neighbors are up to. But you want to know everything.
In Beyond the Doors, your job begins every night right when your neighbors shut their doors and disappear. Place recording devices near their doors. Build a chain to transmit the sound back to your basement office. Collect, analyze, and send these sounds to the people who request information from you each day.

As you place more devices, your network will grow more complex. It's up to you to set up the right connections and fix broken network. Use the credits you earn to buy upgrades, merge tangled chains, and build the perfect network.

Climb the stairs. Walk the halls. Dig through trash. Sometimes you’ll find random documents or new devices to aid your mission. While doing all this, you may witness some mysterious events. Maybe there is a different universe waiting for you behind the doors you think you can't enter.
