Their bodies transformed to become parts of collective intelligence, presumably controlled by some non-humanoid creatures. The Velian men proved to be resistant to the virus, but they lost their status of free intelligent beings and only existed as suppliers of biomaterial for further gene experimentation and as parts of complex biomechanical systems. The society became now a kind of matriarchal hive.
Now the next quote:
Your main enemies will be the mutated representatives of the weaker sex
Everyone here is assuming that 'weaker sex' refers to women in this press release, and then slams anyone who agrees with that sentiment.
Accepting that as the only reference to 'weaker sex' is just as bad.
Think on it, the women were mutated, but they are in control
of the men. Who's weaker there? The men.
Who are being used as genetic material for experiments here?
Who's to say that genetically mutated men
might not be the enemies you're fighting?
