Can I save Garrus in Mass Effect 2? Is there a list of scenarios I can use?

Ok, so I just finished the game. I didn't do any of the plating things so Jack, Legion and Thane died before I even set down. Then Grunt died, Samara died from exhaustion, Morodin got shot in the head, and Garrus got swarmed. Is there a scenario list that I can manipulate to make people I want survive? In the end it was Me, Tali and Miranda in the squad fighting the human reaper. I didn't even choose Miranda in the final thing, it was Tali and Garrus until he died. Jacob survived because I sent him back with Doc and Kelly and the others. First priority is to save Garrus while keeping Miranda and Tali alive.
