Here is my first try at segmented Any% speedrun of AC3 (4:49:35 RTA/3:35:43 IGT) - mostly using Maglx's route from single-segment run as the main route with some new things that i found.

Mod edit: Real time recounted according new rules. Runs starts when it's 3:52 on first video in the playlist and ends when it's 17:00 on the last video in the playlist.
