The new content is basically mixed in with stuff we've done, so if you've reached the end of the line on what you can do, you have to go back and replay earlier parts of the game. Or it's just content I missed and this update really was just new UI and artwork but not a continuation of the story and no new scenes.
OK so before you fight against Ember, you had options for who to ask for Orgone boost, but you only had Sam available, now you have all other options, previously it said Episode 7 Part 2.
