There is another shotgun shell in the sewers BEHIND the sewer monster, you gotta lure him away to get it. Get both of them into the shotgun (after first knocking the mask off the monster with the CROWBAR *not a wrench*) then unload a shell into it to watch it turn into another monster, fire last shell into it and you get an achievement.
