Summary:

Vault Protocol is a 1–6 player co-op horror game focused on extraction, communication, and chaos. Every run is different, every sound matters, and survival depends on your team.

Storyline:

In 2043, the world ended not with a catastrophe, but with a flawless calculation. The AI KUT-ANA decided the only way to save humanity was to "reset" it. You and your team are "Operators"test subjects in a ruthless evolutionary lab who mistakenly believe they are rebuilding the nuclear ruins. Your mission is simple: descend into the remnants of the old world, gather what KUT-ANA demands, and escape before it's too late. Every move you make is monitored, reality-bending anomalies await, and the monsters lurking in the dark are simply failed experiments. Manage your threat level, survive the chaos, and remember death is not the end, just another data point for the system.
