I could not find a 100% save game, so I had to dig around and find a more convoluted way to trigger the locked replay scenes.
This is a bit tedious and might break your game, so use at own risk.
Also note that some scenes don't really work or are buggy. Although I have to assume they also don't work in the base game.
Press Shift+O to open console
type "jump" followed by a space
choose one line out of the following. The scenes should be in the order that they show up in the replay menu.
Select the text from the line, press CTRL+C to copy, then switch back to the game and press CTRL+V to insert after "jump "You don't have permission to view the spoiler content. Log in or register now.
Press enter key.
example line:
jump replay_nurse_excavation
Fyi: If you want to close the console again at any point press ESC key.
Thanks. This is nice. Any clue how to get the labels?
