The quest for the Monolith guys in Jupiter asked me to talk to the people at Midsummer about shelter. But I've spoken to everyone in the building using every option there is, and nothing happens. When I go back to the Monolith guys, they just ask me to go back and talk to everyone about shelter. I've done this multiple times! WTF AM I SUPPOSED TO DO?
You should talk either to DUTY's commander - Shulga, or to the leader of FREEDOM's - Locky. But they agree to take ex-monolith soldiers only if you have good relationships with Duty or Freedom. You can improve your relationships if you give PDA of dead Duty's colonel to Shulga or Locky. The colonel's PDA you can find at water-cooling tower at Jupiter afer quest for rescuing Duty's detachment (they'll be all dead).
I gave the PDA to Shulga but Duty is still neutral.
Very strange. May be you killed some Duty's before? Give the PDA to Locky and try to ask him about Monolith guys.
