Playing this for the first time (I never got to play the old version) and I have to say I really enjoyed it! The voice acting was amazing (I melted the first time August spoke). I did have a question about the codex entries.
How can I unlock the final codex entry? I've gone through all routes and all endings (at least I think I've gotten them all). But it's still locked. Is it tied to one of the DLCs (which I have yet to get through with everyone thus far)?
