    How to unlock Master and Commander

    (Missable)

    This is best done in conjunction with Defender. You can get the trophy without doing any of the co-op missions, but you will have to complete every side mission, carry over specific choices from ME2 (saving the Collector Base, for instance), and make specific storyline choices (deceiving the krogan and making peace between the quarians and geth). What you want is that by the time you launch the assault on Cerberus headquarters, your effective military readiness (the green bar) is at or above 4000. To make it easier, use the method in Defender and you'll get 3-4% after each mission that you play. Completing about two thirds of the side missions and playing three co-op missions got me over 4000.

    The way that your effective military readiness is calculated is by taking your overall readiness and multiplying it by your galactic readiness rating (Galaxy at War percentage) (OMR * GRR% = EMR). Basically, whatever your galactic readiness rating is, then your effective military readiness will be that percentage of the your overall readiness. If you reach Cerberus HQ with an overall readiness of 6000, but your Galaxy at War percentage is still at 50%, then your effective military readiness will be 50% of that, or 3000.

    If you reach the Cerberus HQ mission and you are not at 4000, I would recommend making an extra save (just in case), completing Defender, and then continuing on with the story. Reaching maximum readiness will dramatically increase your overall asset total.

    One thing to be aware of is that progressing through the story missions will lock out the side missions. The way that you should handle the missions is to do all of the side missions first before completing the story missions (marked Priority).

    If you go into the final battle and do not get this, don't worry. Complete the game anyway. Once you beat it, you will be returned to the point of no return. Go online and start working on Defender. Once you're at 100%, go back and reload your saved game. Start up Priority: Cerberus Headquarters and the trophy will unlock soon after.

  • How this didn't ping for me is beyond me... I'm pretty sure I got most of the assets...
  • i believe this has to do with multiplayer. Galaxy at War doesn't really update until then. Kind of sucks since I did single player all the way through and had pretty much every asset possible. Basically, get your galactic readiness and assets updated through multiplayer prior to beating the game.
  • I got this trophy by doing all the side quest and using paragon options.
  • 100% Readiness and all side quests + paragon options but didn't trigger not sure what to do.
  • well. i did all the quests. including most of the gathering of objects and so on, so i really hope this one pops for me. but when i check readiness. it says that it's 50% . wondering how i could increase this?
  • Have Total Readiness >4000 when you permit Hackett to assemble the fleets. Increase Galactic Readiness by playing Mass Effect: Infiltrator on iOS.
  • I had my effective military strength at 7008 when I had Hackett assemble the fleets. Didn't pop for me. Oh, well. *sigh*
  • I got 100% galaxy at war after finishing the game... how this trophy can pop up to me if I don't have a save before Cerberus HQ mission?
  • It's all about the numbers! All u need is 3500 points in WAR ASSETS and when you start the final attack on the Cerberus base it will pop. But remember if you only have 50% galactic readiness your 3500 is only worth 1750 so 3500 and 100% or 7000 points in war assets when you start the last stand good luck
  • Well, I had 7008 War Assets when I started the attack and 100% Galactic Readiness, and it didn't pop for me, hehe.
  • F- you to the guide's writer, thanks for spoiling the ending, just tried to figure out what this trophy meant.
  • how the hell am I supposed to clear almost every sidequest if they get locked down if you go too further in the story and you are given an aweful journal??
  • In the road map there are 3 missions that you shouldn't pass before moving on. Pretty much I was really cautious and just tried to do every quest before doing ANY Priority: (something) mission. If the galaxy that the item is hidden in isn't on your galaxy map, then its okay and you can proceed. If its a, "I need _____ for _____" quest, check the spectres comp in the embassy and if its not there and there are no other doable quests, continue on and do your priority quest. Important note(slight spoiler?): When doing the mission with Kasumi, don't leave the citadel and just do that mission with the terminals. Its a known bug and pretty much screwed me out of the trophy for this one. Anyway, I love the game and I still gotta do my insanity run anyway :)
  • Failing the mission with Kasumi doesn't necessarily screw up the trophy. Also, I got this after completing Priority: Rannoch
  • You get this to my knowledge as long as the green bar is full. I cured the genophage I did save the the collector this trophy pop up for me with Galaxy Effective Galaxy Strength at 3185 and Galaxy readiness at 50%. I played import my save form ME1 so that to could of contribute, talking to Hacket after saving the geth and quarians it pop up..
  • It does not matter what you do or choose. Your effective strength has to be over 3000. Then you have to talk to Admiral Hacket, asking for the Situation of the Military Strength. So basically the same LividLeon said. Pretty easy to achieve.
  • Mine popped up exactly as LividLeon's. Master and Commander came up right after I finished the Priority Rannoch mission, right after talking to Admiral Hacket. I just asked him "why me" question. My Galaxy Strenth is barely above 3000 with my Galaxy Readiness at 50% (had around 6,000 total), and my green bar is full. I went pure Paragon, and was able to broker peace between everyone (Krogans and Salarians, Geths and Quarians).
  • Hi, I got it after talking to Hackett, before the assult, I told Hackett "Let's wait" then checked my War Terminal and it pop right away. Total Military Strenth 5222 Readiness Rating: 100% Note: I missed couple of side missions, so I think it doesn't matter as long as you have 4000+ TMS and 100% readiness
  • I got mine when the green bar was full, my effective strength was 3397 and I talked to Admiral Hackett after completing Priority: Cerberus headquarters. I had already attained 100% assets in each of the galaxies and completed most of the side missions, I missed 3.
  • how the hell you can make peace between Geth and Quarians? I only had option to stop the upload of Reaper code or to allow it, pretty easy choice so Quarians went extinct but still, how do you manage to get the peace?
  • i just got this after finishing Tuchanka. i was @ 99% ready & was just asking Hackett about Galactic Readiness when it popped. i thought this wasn't supposed to pop till the attack on Earth
  • This was a complete pain in the ass to get. After three playthroughs of doing every mission and not getting it to pop up I read the forums. Finally got it after downloading the extented cut DLC and taking to hacket about galitic readiness. Was after priority Rannock. GR at 95% Effective Military Strength at 6500 About 85% paragon On playthrough with save imported from ME2
  • I just had this pop for me after completing priority tuchanka, GRR about 97% although checking war assets my N7 special ops asset finally appeared. the number seems high though not that I'm complaining or anything I only promoted 8 times tops and it's contributing whopping 2850 to my military strength. I think it must takes more than just promotion in consideration when calculating you N7 spec-ops war asset boost, in multiplayer my N7 rating is 351 with 1,350 challenge points. Point is multiplayer can make this really easy if you sink some time into then you can play the game how YOU want to play it without worrying about war assets. Starting out in MP can be a bit rocky untill you can get some good gear and characters, but once you do it's quite fun especially with a biotic hea
  • So can you still get this of the quarians died??? How do you make peace between them and the geth??? ANYONE?? Im playing thru on insanity. Paragon Mass 2 import. Done all the side missions. Have 50% readiness And about 6000 war assets. And just finished Rannoch. What do i need to do?
  • I didnt understand a thing i am not gonna get this trophy
  • If this doesn't pop and you have over 4000, download the Extended Cut. I think the trophy is glitched and there is a patch for it in with the extended cut. Once I downloaded the extended cut and started up the game again at point of no return the trophy popped as soon as I talked to Hackett. Hope that helps. I was really pissed when mine didn't get it after my 100% insanity playthrough.
  • DOWNLOAD THE EXTENDED CUT DLC with Galactic Readiness at 50%, I got the trophy right after the Priority: Rannoch, with every side mission up to that point completed. You only need to have an EMS of 3100 for the trophy to pop. That said, you don't have to play MP to get this trophy, but still, you need Defender.
  • Got this last night without even playing multiplayer (50% readiness) maybe because I have the Extended Cut DLC. Imported a ME2 character and went paragon all the way, then got the trophy right after Priority: Rannoch. You talk to the Asari Councilor and then to Hackett after this mission, and the trophy comes right away. I had roughly 2900 of overall readiness.
  • I got it as well on my first playthrough(ME1->ME2->ME3 import, Insanity, full Paragon), after Priority: Rannoch and while speaking with Hackett. Total Military Strength: 6998 Readiness Rating: 50% Effective Military Strength: 3499 I didn't expect to get this this early.
  • I'll bet the Extended Cut has a lot to do with this. I got this trophy after completing the Admiral Koris mission but before the Geth Fighter Squadrons or Priority: Rannoch missions. I picked a side in one of the conversations on the Normandy, then talked to Hackett and the trophy popped. EMS just under 3000 with GR at 50%, barely poked at the multiplayer. My Shepard has been 99.9% Paragon (the occasional Renegade choice here and there), carried all the way through from the first game. I've been doing all the side missions and fetch quests possible before each Priority mission, as well as talking to everyone I can, plus the From Ashes DLC and the first two segments of the Leviathan DLC (finished the mining facility, haven't gone back to Bryson's lab yet). For those who haven't had it
  • First run (normal mode and without Extended Cut DLC): failed. EMS > 7000 with RR = 94%. I completed everything beside some mission on Citadel before Priority: Tuchanka. Second run (insanity mode and with Extended Cut DLC): successful. EMS > 3000 with RR = 100%. I completed EVERYTHING (even the other DLCs) I could and the trophy popped while speaking with Hackett, right after Priority: Tuchanka. Too much variables, can't say what was the real thing that solved this issue. I'm just glad it worked, somehow.
