I had finished one of the endings for the game, im working on the next one. But after playing through the game I've been a bit confused by the story. I know the story is accessed through logs, and cutscenes. But I feel like I'm missing so much. Like for example What did Arjun do to sebastion? And what happened to the other echelon groups? And are there other realities? And what are these creatures? I love the game but I think this way of story telling confuses me a bit.
