In-game im often asked how to do the quest and im told that it is broken. This walkthrough is here to clear up any confusion and I'll explain how to do it from the perspective I made it to be done by.
THIS IS A ROUGH GUIDE, NO PICTURES OR EXTRA DETAIL INCLUDED
Head to the cafe and touch the NPC at the table drinking, he gives the clue to go to the drink n forget bar North of Ol'West
There is a poster of my face at the back of the drink n forget bar behind some crates, throw the crates away or destroy them and solve the riddle. Cba? The answer is 'circus' - say this aloud to open up the secret room.
The middle bookshelf hints that there are 5 books missing - this is where people are getting confused. The will not be a detailed explanation to specifically point out where the books are - so here are some brief explanations:
The hotel thingymabob (I said not specific) next to drink n forget has a book in one of their rooms. Pick it up.
The hotkey place next to start has one too, break the boxes. Pick it up.
In the South Indian territory, there is a building next to some abandoned trains. Go upstairs and there should be a book on the table. Pick it up.
Above the 'bank' base is a little building that is kinda irrelevant - to inside and to the left, there should be a book there. Pick it up.
And the last book is at start inside the sheriff's place - go to the jail cells in the back and the top left cell has a book on the table. Pick it up.
There are NO other books, and there are no books in places other than stated here
Go back to the bookshelf once you have all the books - it will do some hocus pocus **** and open up - go inside and read the book.
Tl;dr (you lazy bastard) the book basically said talk to lonely boy, who is located under the bridge.
Tl;Dr lonely boy asks you to find the key to the drain under the bridge. His friend has it - his friend is located at the saloon near the mines - go behind the bar of the saloon and pick up the key
Go back under the bridge now you have the key, and a drain should appear there. If not, reconnect. Grab the drain.
Attempt to woop my ass. If you somehow win by hacking and get away with it - then the waterfalls behind my dead, yet beautiful corpse will collapse and reveal a secret shop where you will still be ripped off for my guns even though you went through all this hard work
PARTY! You now have the sexiest goddamn guns in the game. Show them off to everyone and brag to them if they can't afford it or simply don't meet the skill level required to open a can of whoopass on me.
