How to unlock the Prothean Expert achievement in Mass Effect 3 - Definitive Guide

Non-missable achievement, so long as you play the DLC.

Simply complete the "From Ashes" DLC. This will show up on the Galaxy Map as "Priority: Eden Prime" in the Exodus Cluster's Utopia system, and should become available from the first opportunity you get to set your own destination. Note that the system will be flashing, but you won't see the name of the mission displayed on it unless you scroll over it.

Once you've had a conversation with your new squadmate and the mission ends, the achievement will unlock during the loading screen as you transfer back to the Normandy.

Why are people downvoting this? It's exactly what I needed to know. The anti-dlc crusade has reached a new low. Thanks RT.

For some reason my comment didn't show up; I added the location of the mission to the solution after lunchbox posted his comment. Thanks guys for bringing that to my attention; I forgot the DLC mission wasn't super obvious from the main galaxy map.

I guess a lot of people don't realize that 'From Ashes' needs to be bought as it is not included in the standard edition - that online pass only counts for Multiplayer. Nothing wrong with the solution, people voting negative are either being arse holes or idiots.

Also I think you need to download it from the in game menus (as with the recent MP DLC) if you get it from the Marketplace direct or through the Web front end it doesn't seem to show up :(

I don't know what you mean by it not showing up - it doesn't seem to appear on the Galaxy Map without you actively searching out its system, but I downloaded it via the marketplace and the mission was definitely there.

I don't know what you mean by that - you can't find it on the Galaxy Map?

Same here... I was hoping to play it soon in the game in order to get this good weapon... I will check on DLC menu again - perhaps I have to activate it somehow...

Update: I found out that the DLC was not installed properly. I bought it directly in the game and when I checked on it in the hard drive space overview there was a yellow "!". So I downloaded the DLC again in Marketplace. This time it worked out and the mission showed up in game.

Then something's glitched for you, and I don't know how to help, sorry. It should pop; there are no special requirements other than simply completing the mission. If you plan to get Leviathan, maybe try it after installing that, or delete From Ashes and then re-download and install?

Story related, can't be missed.

Besides finding the intel, all you have to do is fight your way through and open the pod at the end. This is basically a side quest in the game which gives you an extra squad member.

Story related. If you want more info, continue reading. Otherwise, know that this will unlock through the natural progression of the story.

Mission - Priority: Eden Prime

This is acquired after you have free roaming in the Normanday. You will receive an email telling you about Cerberus interest in Eden Prime. Go to the Exodus Cluster to find Eden Prime.

Insanity Tips:

  • It is not necessary to complete this mission on Insanity as it's not required for Unwavering. However, if you are working on it during the main story, then you will have to.
  • Stay in the buildings and pick off the Cerberus enemies. This will protect you from being flanked.
  • Protecting the stasis pod is the hardest part of the mission. You'll have to deal with a couple of waves of assault troops and centurions. After the first wave is gone, then an atlas mech and more troops will show up. Hide in the nearest building to get a good amount of cover to drop the enemies.

The story trophy will be given after the Prothean joins you at the end of the mission.
