▶▶ Pod 153 - Report:

The machine lifeforms not only infected the YoRHa soldier units on the ground, they also infected the <Bunker> with a viral attack, activating a self-destruct sequence.

With this, the 13th Orbital Satellite Base <Bunker> was destroyed. 

2B and 9S avoided infection from the virus and escaped the Bunker before it was destroyed. 
Proposal: Find the remaining surviving YoRHa Soldiers and start another descent-to-ground operation on Earth to fulfill the mission.
So I don't usually get a partner.
It's kind of fun!
‫لذا لا أحصل على شريك عادة. هذا ممتع نوعًا ما!
Es kommt nicht oft vor,
dass ich einen Partner habe.
Ça change, d’avoir un coéquipier.
Quindi, poter fare le cose
insieme a qualcun altro
Por isso, quando dá pra
trabalhar junto com alguém...
У меня никогда не было напарника.
Это так весело!
