So if you do the steps I outlined, and keep your "hold the line" party average at 2 or higher, leave Jack to help hold the line and she should survive. Non-loyal ones will fall first, followed by loyal ones, in this order. The order of death is Mordin, Tali, Kasumi, Jack, Miranda, Jacob, Garrus, Samara, Legion, Thane, Zaeed, Grunt. If the average is 0.0, all non-party members will die. If the average is between 0.0 and 0.5, three non-party members will die. If the average is between 0.5 and 1, two non-party members will die. If the average is between 1 and less than 2, one non-party member will die. If the average is greater than or equal to 2, everyone holding the line will survive. Jack, Kasumi, Tali, Mordin - If loyal, 1 point each.


Thane, Legion, Samara, Jacob, Miranda - If loyal, 2 points each. Grunt, Zaeed, and Garrus - If loyal, 4 points each. The party average needs to be greater than or equal to 2 for everyone for survive. It'll all depend on who you have holding the line in the final mission. Don't take Jack to the final boss (non-loyal party members will die). Don't send Jack to escort the crew back to the Normandy (the crew will survive, but the escort will die if not loyal). Jack is second on the list of who will die). Don't chose Jack as the biotic specialist in the final mission (if non-loyal, someone will die. Upgrade the Normandy's ship armor (whether loyal or not, Jack will die if this isn't done). I see you've got plenty of hours in the game, but I'll make this as complete as possible for anyone else who sees it.
