So, I know of the four from the first one: teleporter activation, the antlions, necromancer and Magnusen's Nuke.

But what are the other 5? I got one by kinda trial and error: one after you kill GMin (the borked HL2 credits), and two events with papa Grigori (the one in your room after you shoot the cheaple in his basement and the one in chappel after you kill Grigori).

I know of theelections, but do they repeat?
Also for some reasons the Open the Jail and Infestation buttons in Breen's room don't work and what is the button near the window overlooking the teleporter room?
What's the deal with the doomsday prophet that can spawn, event or some ending?
And what's the deal with the dolls? Are they an ending or just eastereggs?
And does going to bed bring new thing each day or not?

Anyone has tips for other endings? Tips for triggering more events?
