Rescue Mantis for the Mutants, purgue the Hive.
Ahah, totally reverse for Me)
At least Hive relations are simple in terms and goals, trading such alliance for a random girl, and... MC care not 'bout her, she care even less 'bout MC, so why? not a Hard decision for distopian morale
Ofc I have 2 saves with different routes through game. So I ofc tested both and:
I can't find a reason for my MC to care 'bout "hivegirl" and same' bout "already Mantis"
No sympathy for Fangs also.
I can't even feel MC as part of that mutant group, and tbh even raider girls care more 'bout MC (at least some humans attitude) and have some connection.
Edit: And c'mon is MC Alpha in dystopian sociaty or Beta schoolboy in shonen anime? How many "princesses" he must save in mutants storyline totally without any fuckin' reason to do that?
So... after expressing my (wall of text) rough thoughts, short conclusion:
At least Hive content is most interesting content in all "mutants storyline" and can possible guide to interesting situations in future.
