About this game

Office 21 is a first-person horror survival horror game that forces you to work a shift in a mysterious office building where every aspect is abnormal.

Very similar to Five Nights at Freddy's, you need to manage an office and ensure things don't go wrong.

Explore a large Open-World area to find secrets and go to different locations.

What begins as an ordinary day at work quickly turns into a fight for survival as the building malfunctions and the employees who once sat in your position become something else entirely.

Survive across multiple nights, each introducing new mechanics, entities, objectives, and threats. Explore the dark office or stay inside to deal with the dangers yet to come. Your power is limited, so be mindful of conserving your resources in order to make it through the night.

As the night progresses, deal with floods, broken phones, a frozen office, lingering entities, and survive for as long as you can before finally leaving and clocking out.

No night plays out the same. Dynamic events and unexpected encounters keep every night interesting and unpredictable.

Features:
• Multiple unique nights
• Atmospheric first-person horror focused on tension and suspense
• A dynamic event system that changes your experience
• Challenging survival encounters against the Awakened Workers
• An immersive office environment filled with interesting areas to explore
• Gradually escalating difficulty as the night progresses

The clock is ticking.

They're already here.
Something's hunting you. Search the office. Use what you find. Survive the night
