One thing I noticed on my first playthrough was that there was never a proper “title” for Lambda Core. I also noticed the same thing happen during Podcast 17’s playthrough as well. I even went back and started a new game from Lambda Core and saw no “Lambda Core” chapter title appear anywhere. Don’t know if this was an over site or intentional though. And I haven’t seen anyone else mention it either.
Don’t recall if I saw a chapter title myself or not.
Although, to be fair… there is a giant sign as you walk into the place reading LAMBDA CORE. Maybe they thought it would’ve been a bit silly if you had a text overlay saying what was already in huge letters before you.
