Gilda's Lost Axe quest glitch
When you first arrive at Mean Street, talk to Gilda, the cow lady who is located in front of the Fire Station. You will need to talk to her multiple times in order to begin the quest. If you recover the axe in the "Slopes" area during your ascent up the mountain you willl ned to thin out the giant Oswald face when you reach Oswald's lair to reach a hidden room. When you come to the end of the corridor in this room, you'll find some large, unthinnable metal bars, and Gus will offer you the opportunity to use Gilda's axe here to explore this area further; don't do this. Instead return it to Gilda and upon returning to OsTown. When you return to the Mountain later in the game, thin out the Oswald face again and go back to the bars. Gus will still think you have the axe, and you'll be able to use it to pry your way in and explore! You'll now be able to reap the rewards of both the "hero" and "scrapper" outcomes of this quest, while it will be officially recorded in your quest log as having gone the "hero" route.
