Backrooms

Survival horror for Hytale.

No one knows where you are or how you got here... But one thing is certain: you must collect 3 keycards from the vending machines, use them to activate the elevator, and get out of here. Mine food from blocks, survive, hide...

Gameplay

• Find 3 keycards hidden in vending machines — beat the skill-check to claim them.
• Activate the elevator with all 3 keycards to escape.
• Eat to survive. Hunger drains over time. At 0 food you take damage and your stamina stops regenerating, so you can't run. Stay above 90 food to slowly heal.
• Mine food from blocks scattered through the level.
• Survive the dark. Lights cut out on a timer and monsters hunt you in the blackout.

Requirements

1. Hytale installed via the official launcher.
2. Java 25.

If Hytale is not installed in the default location for your OS, set hytale.home_path=/absolute/path/to/Hytale in gradle.properties (use forward slashes).
