Can someone explain how you unlock all the Zhokhar scenes? I didn’t even know they were in the game until now. Is it possible to unlock them on Mascen’s route or do you have to do something different?
...No, you can't unlock Zhokhar's scenes while pursuing a romantic relationship with Mac. That defeats the whole point of a romance route.
If you want to start unlocking Zhokhar's Spiceport scenes, Killigan must be single when going into Spiceport City. You can easily do this by skipping to the beginning of Spiceport in a new game.
