You traverse through tunnels and reservoirs, past a few shanties, and finally come upon the Marconi Castle. The large structure is built at the bottom of a large, dried-out sewage keep, and is made up of rusted metal, plastic, and glass. It is all held up well, and Marconi goons patrol upon balconies and scaffolding, Kriksboc-19s and M-26 Carbines toted in their burly arms. The Castle is in front of you, and you are in a small sewage pipe leading into the keep. The goons do not notice you.
