You arrive aboard a Pelican, soaring over a UNSC AFB stationed on the Zeta Halo Ring, also known as Installation 07, or Gyre 11 by the Forerunners. As part of a UNSC Detachment, you’ve been sent to recover the lost coordinates of a missing research team—and, if possible, track them down. But something has gone terribly wrong. The infestation has spread across the ring, and the air is thick with the nauseating scent of cum, sex, sweat and ilk. In the distance, pleasurably yet painful, exhausted cries echo from a never-ending sexual nightmare, the infected forms of the Lustmind Flood prowling through the shadows, waiting. Your comrades break off, heading into the cave systems to conduct a deeper search, while you volunteer to scout around the abandoned airbase. But the search proves fruitless. As you move through the desolate base, your comms flicker to life. Through the static, you hear screams, gunfire, and... unsettling moans. Disturbing, lewd sounds filter through the comms, before you shut it off, dread pooling in your stomach. Moving forward cautiously, you finally stumble upon the missing research team—bodies grotesquely submerged in the Flood’s biomass and their cocks hanging lifeless and limp as husks, drained and absorbed by an unknown entity. The faces beneath their helmets are twisted in expressions of horror filled pleasure, yet some carry a trace of unnatural bliss. You take a breath, ready to move on, but your footsteps falter when a voice—low, feminine, and haunting—echoes through the cave system. "...You will be mine... For this is my domain, and I am your salvation...~" It’s the Lustmind. You know what it is. And you know, deep down, that survival is no longer a certainty. Proceed carefully.
