Wild Bill

Wild Bill is a dead slave found in the The Pitt. He carries the unique Wild Bill's Sidearm and a Note from Wild Bill explaining his death to Milly.

Bill seemed to be kind hearted & heroic due to the fact he volunteered to gather Steel Ingots to save other slaves from being killed by the Trogs. According to the note found on his corpse, the trogs were easily dispatched and the steel was easily gathered, but the Wildmen finally put him to rest. Strangely, they didn't take his sidearm.

Wild Bill developed a keen relationship with a fellow slave Milly, as their time in the Mill together was some sort of a bonding experience.
