Is there a different way to find Ruby's hideout other than the Shivers check at the Feld building? The game really wants you to pass this check. At the end I had 8 bonus points from other quests. But even with the highest possible chance, 1 in 36 players are still going to fail this without any fault of their own.
Apparently not. And I think you could actually end up stuck, if you don't make the check, don't have any points left to spend but have exhausted all side-quests. Unlikely, but possible.
Related to that, what would happen if you just sat around for 5 days doing nothing?
Probably not that much, I guess? But then, who knows, maybe Kim gets too annoyed eventually.
The biggest issue might be advancing time - I guess one would have to re-read some book several times since you can't skip ahead with Kim around (esp. annoying when you want to meet The Pigs).
Is it possible to end the tribunal peacefully? Would Kim have died if I had failed
this check?
No, best thing you can do seems to be to limit casualties (not that much, however). If you fail the check, Cuno turns up instead and tells you Kim is in hospital. You get to finish the game with Cuno at your side.
And who is this Ruud Hoenkloewen at the tribunal? He came out of nowhere and was acting very strange.
Not sure. I'm wondering whether you can find some hints about him before the tribunal.
Joyce said they are working in teams of three, so only two should remain. OTOH, they had more than one week to fly in some backup, so maybe that's what they did?
Pretty sure he's not the deserter, since Ruud is shot through his visor and killed by Kim, while the deserter definitely doesn't seem to have any facial injuries.
