Until Dawn - Alternate Tower Scene with Flare Gun(Details in Description)

IMPORTANT(since I forgot to include) - First of all, you mustn't agree with Emily's plan to head to the radio tower, when given the dialogue option to agree or disagree with Emily's plan to head there, earlier in the chapter.
Make sure to do this step, prior to the flare gun option on the tower, otherwise, Matt will just automatically shoot the flare regardless on the top of the tower, causing this option and scenario to not exist in the cave and also causing Matt's death if he decides to help Emily in the collapsing tower.
