Quest

A merchant told me there is a lot of Spacer activity in the Altair system. He also heard an urgent distress call. I'll have to go to Altair to learn more.
Objective: Go to the Altair System

I heard a distress call from Private Mahoney. There is a Freestar Collective research outpost on Altair II that has been overrun with Spacers. They urgently need help.
Objective: Land at Research Outpost U3-09 on Altair II

I found Private Mahoney, but the whole research outpost has been overrun. Mahoney said I need to make my way to the makeshift infirmary on the first floor and talk to Lezama.

The outpost's infirmary is secure. Next up is rescuing the Freestar Militia's commander: Lieutenant Torres. He's on the third floor in Doctor Moussa's office.
Objective: Clear the Spacers outside the infirmary and talk to Lezama

Lieutenant Torres wants my help to rescue a United Colonies marine named Captain Myeong. These unlikely allies have been fighting the Spacers together. She's on the second floor guarding the other entrance to the outpost.
Objective: Find and rescue Lieutenant Torres

The outpost is secure. The soldiers are going to fortify the outpost for the next Spacer attack. Lieutenant Torres has asked me to rescue some people at a Research Camp elsewhere on Altair II.
Objective: Eliminate the Spacers at the Research Camp

I've saved the Research Camp. I should report back to Lieutenant Torres and see if he needs more help.
Objective: Talk to Lieutenant Torres

Preparations for the next Spacer attack are under way, but unless we take out their spaceships they will be able to reinforce themselves until we're overwhelmed. There are two Spacer attack groups I need to take out in orbit of Altair I and V.
Objective: Defeat Spacers in Altair I's orbit

The Spacers no longer have any spaceships in the system. I need to get back to Research Outpost U3-09 and hope I get there before the Spacers attack.
Objective: Land on Research Outpost U3-09

The final Spacer assault has begun. We need to clear them out so that the Outpost is finally secure.
Objective: Defeat the Spacer Invasion

At long last, the Spacer threat in the Altair system has been taken care of. I should talk with Lieutenant Torres.
Objective: Talk to Lieutenant Torres
