Heyo, I'm wondering if anyone could help me out?
It's entirely possible I'm misremembering, but I thought that there was a reference to Prometheus in Isolation in the form of a poster on a wall somewhere within the game? I know there's adverts and posters everywhere on Sevastopol, but if I am remembering correctly, the poster was either pinkish or purple-y and it was for a band, or maybe a movie, named The Promethean Fire or something to that effect?
It's also possible that it's a poster in one of the Dead Space games, in which case it wouldn't be referencing Prometheus, but I definitely thought I came across it in Isolation at some point.
Let me know if you recall seeing it, too. Thanks!
