The wiki lists the conditions for the "Core City in Chaos" ending as "Archibald Knight is alive" and "Archibald Knight knows Miland Simmons killed Edmund Knight".
I'm curious if there are alternative ways to fulfill the second condition. For sure, if you join the Praetorians, then doing the Cube quest will give you an opportunity to inform him. But given that this fact can influence the ending slides this much, I feel there has to be other ways.
