Yeah. They should have had that in the motion comic. Do they let you chose if the Rachni queen lives or dies?

Yes, here's the events you get to choose on:

Romantic relationship with Kaiden/Ashley/Liara

Saving/killing the Rachni queen

Saving Ashley/Kaiden

Saving Wrex

Saving the council

i LOVE Mass Effect. the only thing i regret in my ME2 game was doing the leftover missions before going in to the big last mission. now all my crew including that cute assistant i had is dead :,( i think i might do the last run on a previous save if i have one, i need to get ready for 3!

I did the exact same thing. I need to go reload one of my previous save to rectify this. Crap now I want to play the game again haha.

Before you get legion make sure you have done any and all side missions you wanted to do. Then make sure you have done ALL of your teams personal missions. This means once you get Legion, you talk to him and get him to tell you about his mission. You then do this RIGHT AWAY. Do not do anything else but legions mission.

I've done the last mission with Legion surviving, and I didn't have his loyalty.

But how many of your team died?

None. I had all of their loyalty missions done but Legions. I'm usually super careful during the suicide mission.

Did you use legion to do any of the tasks in the final mission?

Nope.
