Dossier: The Thief – You’ll want to go to the Citadel at this point in the game.

Project Firewalker – This one can be done anytime before the Reaper IFF mission as it's not that important.

Therefore, you may as well find the vigilante after you've got Mordin.

Dossier: Archangel – Recruiting Archangel is the last vital thing to do on Omega in the early stages.

Logically, Shepard wouldn't go for anyone else first besides Zaeed.

Dossier: The Professor – Picking up Mordin Solus early makes a lot of sense because, at that point, he's the most valuable person to have on the team as he can help deal with the Collector seeker swarms.

Thus, there's no need to ignore the veteran merc.

His dossier 'quest' is just a simple conversation. Zaeed is near the entrance to the space station, and you're guaranteed to pass him upon entry.

Dossier: The Veteran – Three of your future squadmates are on Omega, so that's where you should head next.

Although, it seems more appropriate to visit the wreckage of the original Normandy to say one last goodbye before getting into the game.

Normandy Crash Site – A few characters suggest that your first objective should be to head to Omega to meet the Professor.

RELATED: Mass Effect 2: Every Squad Recruitment Mission, Ranked You also have a few other quests to keep you busy. Things start to open up once the prologue ends as the Illusive Man gives you multiple recruitment missions to do at your leisure.
