I actually found 2 more endings which weren't written in the walkthrough. They are both in resistance endings. To get them while you choose the "Back to Normalcy" route you need to fail the QTE against Samantha and against Brock. That will lead Brock's ending if you accept his offers. The second one is with Ralph. Here is the way to achieve it: " Refuse to tell her more → Look for a trail to Maya at the club → I shouldn’t get involved with him → Decline" this one will lead 1on1 with Ralph the casino owner. I'm not sure there are more endings but it is for sure more than 17. If you managed to find some more you can enlighten me aswell. Hope you enjoy it, great game.
