HAL Protocol

HAL Protocol is a first-person narrative game about finding your way through a repeating corridor aboard the HIS 01 Echo. Your shift is over, and the return shuttle is waiting in Compartment 9, but the corridor keeps bringing you back to the beginning.

Spot the changes

Each cycle alters something on the ship: an object may be missing, a wall may be in a different place, or equipment may have moved across the hall. You observe the surroundings, remember what you have seen and use your intuition to identify anomalies. Spotting them is the only way forward.

Break the loop

There is no time limit, so you can explore at your own pace. If something is wrong, turn back; if everything looks right, proceed. Choosing incorrectly resets the loop. The game has no enemies or jumpscares.
