    Since the Prima guide was utterly useless for figuring out the endgame and there seems to be a great deal of confusion on the boards about how this works, I thought I'd spend some time running different teams through the endgame to see what variables are at work.

    Space Battle.
    If the Normandy is not properly upgraded, each missing upgrade will result in a team member death before you even start the assault on the Collector base.  If you take this team member with you during the oculus fight, or haven't recruited them, or they are dead, a different character dies instead.

    -No Silaris Armor:  Oculus beams punch through; Jack dies.
    -No Cyclonic Barrier Shielding:  Engine core overloads; Tali (or Legion or Thane) dies.
    -No Thanix Cannon:  Normandy charges in with main guns;  Thane (or Garrus) dies.

    Base Assault.
    For the assault itself, there appear to be three types of characters that are required for the various key roles: 

    -If the Tech Specialist is not one of those listed below, they will die at the first rendevous. 
    -If the first Fireteam Leader is not a leadership character, the Tech Specialist will die at the first rendevous. 
    -If the second Fireteam Leader is not a leadership character, they will die at the second rendevous. 
    -If the Biotic Specialist is not powerful enough, one of your current squad members will be swarmed by seekers and die. 
    -If the crew survivors are not escorted, they will die (any character can do this and the crew will live).
    -If the Heat Exchanger valves are not opened in time, the Tech Specialist will die and you're forced to restart.
    -If there aren't enough Combat Specialists left behind to hold the line while you fight the last boss, characters die
    -Some characters are worth more as Combat Specialists than others; these point values are still being tested
    -Characters with low point values are the first to die if there aren't sufficient points to hold the line

    The following characters are the only ones that will succeed at their respective roles:

    Tech Specialist
    * Tali
    * Legion
    * Kasumi

    * Miranda
    * Jacob
    * Garrus

    Biotic Specialist
    * Samara / Morinth
    * Jack

    Crew Escort
    * Any loyal character

    Combat Specialist
    * Zaeed
    * Grunt
    * Garrus
    * possibly other partial contributors

    Disloyalty (Normal Loyalty).

    Not having a character's loyalty has different effects depending on what you do with them:

    -Having disloyal characters in the above key roles will result in deaths, regardless of whether they are suitable or not.
    -A disloyal crew escort will sacrifice their lives to protect the crew (the crew will still make it).
    -Disloyal characters don't get as many 'points' as loyal characters when holding the line and are more likely to die
    -Keeping disloyal characters in your active squad prevents them from dying, except for...
    -In the final boss fight, disloyal characters in your active squad will be crushed by rubble after the fight and die.
    -If all team members are dead, Shepard misses the final jump and lets himself fall to his death rather than risk Joker's life.
    -Note that with all 11 team members recruited, it's actually not possible to kill off all of them and get yourself killed.

    Kidnapped Normandy Crew. ( Not essential for the achievement)
    If you do not go through the Omega-4 relay quickly enough after the Collectors kidnap the Normandy crew, the captured crew members will die off in the endgame.  Watching Kelly get liquefied was particularly horrifying.  Who dies depends on how many missions you did after the Joker level (actual clock time does not affect the outcome, nor do relay jumps, fuel spent, or landing on Illium/Omega/Citadel/Tuchanka; any quest, big or small will count though):

    -If you use the relay immediately, everybody survives; Horizon colonist gets liquified instead.
    -If you do one mission, Kelly, engineer Daniels, mess sergeant Gardner, and half the crew dies.
    -If you do two missions or more, everyone except Dr. Chakwas dies.

    Legions loyalty mission.
    Note that if you activate Legion and learn about his loyalty quest immediately after the Reaper IFF mission, the Collector attack / Joker level will wait for one extra mission before triggering.  This allows you to complete all the loyalty quests before the crew is even kidnapped (assuming you did the other ones already).

    The X-Factor.

    Some people also report having trouble keeping a character (typically Mordin) alive at the end, where they must hold the line until Shepard kills the last boss.  This seems to be related to a choice or choices made during the final mission, as rearranging team roles from the same savegame will affect whether this mysterious death happens or not.

    Leo AscendentHold the Line: Grunt, Garrus, and Zaeed (Leave these squadmates behind during the boss fight, and don't give them escort duty)

    This might explain it, I took Garrus as a party member, when he should have been left with Grunt.

    Leo AscendentSorry for spamming, thought I'd post a link to where I got that info above.

    I'm done now, lol

    SockGORE828Had the same problem as leo with Grunt, but I had left Garrus behind...

    O.K. All of these suggestions are very good but I have the solution to the problem people are having with the fight between Jack and Miranda. The solution is somewhat easy. First off make sure that you put off either Miranda or Jack's loyalty mission until the very very end.

    I played through as a vanguard and I noticed that the assault power that the vanguard has could be evolved into "champion," which gives a %100 bonus to your paragon or renegade score, so it basically doubles your score. This means that it is only necessary for you to get your para/rene up halfway as long as you have evolved it into champion before you get involved in the fight.

    If you are successful in doing so then you will be able to choose either a para/rene option during the fight. This will diffuse the situation and keep the loyalty of both of them.

    This same situation will also come up between Legion and Tali. If during that fight, you find that you cannot use one of the options, do not fret! There is a solution. I believe they do this simply so you do have to make a game changing decision. To fix this simply walk up to the person you didn't side with and select to talk to them about the fight. Then select the para/rene option. This will fix the situation and that person's loyalty will be yours once again.

    Now for the people that did not know about this fight and sided with Jack/Miranda. You can fix this by doing the same thing that I mentioned to fix the Legion/Tali fight as long as you have %100 para/rene or %50 and assault power evolved into champion. I do not know which classes this will work for because I am not sure if they all have an evolution that doubles para/rene scores but I can confirm that it will work for the vanguard.

    These were my choices for the final suicide mission:
    Specialist (person going through the tunnels): Legion
    Second Group Leader (fire team): Garrus
    Personal Group (people you fight with): Samara and Grunt

    Escort (survivors back to ship): Mordin
    Specialist (biotic shielding): Jack
    Second Group Leader (fire team): Garrus
    Personal Group: Miranda and Legion

    Take with you Miranda and Legion

    *Make sure you choose Garrus for both fire team leaders and also make sure they are all loyal!

    LukaztroI just want to add something for anyone still trying for this achievement. I ran into the Mordin dying problem on my Insanity play through. I went to the load screen, restarted the mission, lowered the difficulty to normal, and ran through with Mordin as a squad member with Miranda. Achievement popped after talking to Illusive man! PS thanks for your guide. big time saver!

    I x ShockWaveZI went with this one as the original wasn't completely accurate despite being discrete.

    Mordin always died for me so the alternative was as you stated to send him back with the surviving crew members.

    Achievement popped on my 2nd play though and this was on insane so got 3 separate achievements for 225G and reached the 1000G for the game so that's me happy.

    Thanks for the advice.

    Zeta SighThe guide was great for me until the end where Mordin died. I reloaded and took him and Miranda to the final fight and he survived. I've read around the web that he has the lowest 'hold the line' score. So if he has to hold the door before the final fight then he's [retty much a goner.

    Here's how i did it without having Zaeed and Jack's loyalty:
    1st Choices:
    Tech Specialist - Tali
    2nd Squad leader - Miranda
    My Squad - Thane & Jack

    2nd Choices:
    Survivor escort - Legion
    Biotic Shield - Samara
    2nd Squad leader - Miranda
    Finale Fight - Thane & Samara
    I choose the Renegade option in the end, i don't know if it matters, but there you have the recipe for "No One Left Behind" without the loyalty of Jack and Zaeed :-)

    l306l PoRkRoAsTGreat Guide, the key to this is to have your final battle team made up of Thane and Samara this prompts Jack tolead the dialogue in the cutscene and she won't die.
