"'I've never seen people like the cleaners, being able to burn everything without remorse, they think they're some sort of heroes, what bullshit. I do have to admit however, they're efficient and handy. I just hope that i won't ever have to face them again.' -Sergeant Thomas Avery, 9th guard company, level 53"Level 53 is the site of a massive operation performed by the cleaners who broke into the level and burnt everything in sight in order to rid the place of disease. Civilians and guards were burned alive, and the battle got so large extra forces had to be sent in.
