Behind the scenes

 * Once you have collected all 100 Steel Ingots, Everett will say "Yup, guess you got every last one out there. You're one hell of a steeler, kid." "Steeler" is a common name for a worker in a steel yard and is also the name of Pittsburgh's professional football team.
 * When giving you the Mauler, Everett notes that he had killed Trogs with it 'from here to Monroeville.' Monroeville, Pennsylvania is the city where Pittsburgh native George A. Romero filmed the classic 1978 horror film Dawn of the Dead.

Bugs

 * In some cases Everett won't go into the Mill where you have to give him the ingots preventing you from finishing the quest. In this case, just keep the ingots you've collected, and advance through the storyline. After you defeat everyone in the hole, return to Everett and he'll congratulate you. At that point, his conversation options will return to normal, and you can exchange your remaining ingots.
 * If the last few ingots are presented in a quantity less than 10, you may not get the achievement, and have to kill Everett to fix this problem.
 * When on the building which has 12 ingots, it is possible to fall through the roof straight to the ground which kills you instantly. This bug occurs if Point Lookout has been installed. A solution is to save the game while on the roof, restart and load the save.
