You'll need to play 3 again. i keep the last version of each part, so i can always go back and either look at the gallery or replay. they all share the same save file folder. so you'll need to keep your saves in line.Question:
I'm wanting to revisit the red trifecta in the last part, is there any way to see it in the gallery for part 4, or would I need to go back to part 3 and play it all through again?
