Yeah I've been playing for a few weeks and finally got endings 3 and 5, but have no clue on how to get 4. Have you found anything new?
Sorry for the late reply.
No, as I haven't played in a while; I'll get back to searching, though.
EDIT:
Perhaps, just maybe, if you survive an OBSCCENE amount of rounds, then you'll attain the fourth ending? Or possibly kill the aristocrats without any upgrades?
