I think there will be more, just not yet.
This actually feels a bit like a stop- gap activity tbh... the fact it had a computer-generated voice for the logs, even though that was explained in those logs, screamed a bit of "voice actors have just come off leave from chrissy and have a backlog of Odyssey work, so couldn't do this one"... I'd argue the fact the logs explicitly explain why it's a computer voice is a bit of a guilty- conscience move, but that's a bit of an unfair claim too.
Guess we'll see later this week if something comes up.
Probably going to sound like a noob here (it's not the first time and I doubt it'll be the last) but I've seen it mentioned that the logs are spoken, albeit in a synthesised voice - I've been there and scanned the various points, got the 4 logs but no audio. I can play them back from the codex and hear the audio but nothing when I originally scanned them. Is that how its supposed to be, or am I missing something?
