Completed the main story line yesterday.
I had everyone Loyal, and got the Paramour achievment (Xbox360) with Tali.
Unfortuantely though, I lost Grunt and Mordin during it. D:
I sent Grunt through as the second team on the Second section.
I also had Mordin stay back on the final fight.
Ashley Williams was a complete Bitch when I met her again. Everyone else from the last game and this, when asked about Cerberus, asks you about it. If you say you're not working for them, or you're not doing it for them, they believe you. She (And Kaiden Alenko, if you had him saved in the last game) are complete prats and won't listen to you at all. Gay.
And I needed Kelly to feed my fish. They kept dying when I forgot to feed them. D:
Turns out you need specific team members at certain points. Something like having Samara or Jack for the Biotic section, and Tali or Legion on the Beginning Tech section through the pipes.
Apparantly Mordin or Jack tend to fail at the end, so it's best to either have them with you, or have had them on escort.
I do however enjoy the new Resource section of it. Element Zero is a bitch to find on most planets. I only ever find it on planets that mention that the have it in their description.
The best part about the Probing for Resources if the Sol System Gag.
Head to the Local Cluster, which is the Sol System. Move your ship to Urstar fish. Start the Scanner. Fire a couple of probes and listen. :D
