That’s weird, I saw a quite interesting ending in my dream a few nights ago
I will tell you what I remember
Captain Allen captures Connor and sends him to the camp. There Connor sees Kara, Alice and Luther. He gets a choice whether to help them or not.
If he chooses to help them, he becomes a deviant and attacks the soldiers. Kara’s group runs to the fence. Kara gets a choice whether to leave Connor or help him.
If she chooses to help, she attacks the soldiers and if player wins most QTE for Kara and Connor they run together to the truck and leave.
I know it’s unfinished. But still it’s quite nice for a dream
