Located across the prison complex on the main island are a number of ceiling containment shutter vents. These seem to be holding back an REDACTED, perhaps something that has escaped from containment. Activate a switch to open the shutter vents, and long, limb-like tendril appendages seep through and dangle, waiting to be brushed against. Perpetually hungry, any zombies wandering under these tentacles are grabbed and dragged upwards into the vent for a bloody feasting.
