INFRA: Underground is a 5-map mod for INFRA. A few months after the events in INFRA, Stalburg is experiencing intense storms and flooding. Mark gets a request to check some houses in Raft Isle for storm damage, but there's something unusual about the request. Quickly, your task turns into a fight for survival. Can you escape the underground? Grab your flashlight, camera, hardhat and get ready to crawl through a deadly maze of forgotten tunnels and maintenance areas while uncovering the secrets behind recent water supply contamination.
