This game is a revival of Discovery Island: UnderGround and is a Five Nights at Freddy’s fan-game.

It’s 1999. You are Greg MacLochlainn. After surviving the events at the island’s Power House, you disappear into the Service Annex, a buried maintenance complex beneath the park. Hidden in a forgotten office off the utility halls, you convince yourself you’re safe, until a familiar presence starts moving through the rooms around you.

Unless you are running on a Windows 98 laptop, you can run this trust me.
Discovery Island: Underground is a Windows game
You should have at least 6GB of RAM
At least 1GB of free space
Discovery Island: Underground is a revival of FUTUREe3's game, created to finish what they started and to serve as a love letter to both the creator and the game itself.
The gameplay follows the classic Five Nights at Freddy's formula. You are stuck in your chair, forced to rely on the camera system, learn each mechanic, and survive the night.
