Thanks for the answer, I had to create a new game, and I came in from the last save and started 1 episode. Is this the only special episode? You are not planning to add Weapon mod?
Sadly, there's no visual archive of how Weapon functions in the game, at least as far as i know. I usually work by recreating scenarios and sprites through screenshots, video footage and a description of how it plays, to make it as close to the original as possible.
