Once you make a game you need to start finding about Alien Races here is a list and how to get them.
NOTE:These are not in order so be sure to read them all first.

Turians: At the very beginning of the game, talk to people about the Spectres and Saren.

Asari: Either talk with Captain Anderson, or with Avina [The VI about the council races].

Salarians: Talk to Captain Anderson after the first meeting with the council.


Rachni: Talking with the VI near the Krogan Statue about the Krogans, the rebellion, and the war.

Batarians: After acquiring the Normandy, talk with Captain Anderson. Ask him about him becoming a Specter.

Elcor: Talk to the Elcor diplomat Calyn in the embassy. The embassy is to the right of the Human Embassy.

Geth: Ask Ashley AFTER finding her on Eden Prime.

Hanar: Either with the Preaching Hanar, or with the Shop Keeper that is Hanar. Ask him about his speech.

Keepers: Ask Avina near the Citadel Tower light.

Krogan: Automatic by watching the confrontation between Wrex and the Krogan bouncer in Chora's Den.

Quarians: Talk to Garrus in medical center.

Volus: Talk with Avina outside the embassies.

There have been complaints stating that I have copied this from, which is true. I do not take any credit for this guide.

Leo Ascendent Yes, let's make every bit our own. Sarcasm.... There aren't other ways to do this so why bother rewriting all of it?

The Stig DC Man, missing that first entry from Nihilus is such a drag! At least with this guide I know what to do on my second playthrough.

Grimslinger19 I talked to Anderson about the Protheans in the beginning and even though I have done that the Protheans are still not showing up in my codex. Ecerything else does, but the Protheans never do. And i'm not sure what i'm doing wrong

SecondHALONICK When are you talking to him about it? You should talk to him after being told what the mission is really on and Nihlus should be in the room.

Lockyz75 thanks for pointing out you have to speak to anderson before eden prime

RedSVO Talking to Anderson BEFORE eden prime IS not detailed in the aolution which is why I appreciate this site so much. More detail in most cases IMO. I missed this one and only detail on my first pass, so I get to do it again. Thanks for the solution!!!

ChiefMelee I was able to get the Prothean Codex by talking to the soldier standing by Dr Chakwas right before heading to the bridge to speak with the captain. Just investigate everything and they'll mention the Protheans.

Solario32 Thanks for the list. Everyone looks at ta and biggie.

Fafhrdd All work should be credited if all you did was a copy and paste. Someone worked hard and took time to actually make it... the very least you could do it credit them.

Fafhrdd "Salarians: Talk to Captain Anderson after the first meeting with the council." If you have not received your ship he will be at the loading docks, just discuss his history with Saron. If you missed the chance don't worry you can see him in Udina's Office.

MiTYH Nice guide. Wanted to add that if, for some reason, you missed the Batarians and never spoke to Anderson about them (like I did), you can learn about them by playing the "Bring Down The Sky" DLC. After my first interaction with them, I got the achievement. MAJOR relief since I thought I was going to have attempt and old save to get it quickly

ToXiC JoKeR 92 If you miss getting the Elcor or the Rachni when your first on the Citadel you can get them during your mission on Noveria. The Elcor can be gotten by talking to the Elcor that is selling items on Peak 15. The Rachni can be obtained by talking to the Volus that is in the Quarantine Lab.

The utmost important one is the Prothean one, obtained like it said above from talking to Capt Anderson before the Eden Prime mission at the very beginning of the game.

ThePianoMan73 People who disliked this solution because it originated from x360a are petty. Nice job(: helped me figure out what i was missing!

Who cares if it was pasted (and edited) from x360a. What's wrong with having the same guide in two places? Simply makes it easier and more convenient to find(:

CoXmo Does this have to be in one playthrough? Or will the game carry over the already found entries to the next playthrough?

SecondHALONICK Must (unfortunately) be completed in one play through.

Vanglak This is pissing me off. I have all the races. Still no achievement. This is my 6th playthrough. Yes, I have Protheans in primary codex.
Posted by Vanglak on 20 Oct 13 at 07:52
Redd Five I believe this carries over through multiple playthroughs. It popped for me after talking to the Volus on Noveria about the Rachni. I was working on the squadmate achievements, so I wasn't hunting codex entries at all.

A4TH BrokenHalo Anyone know how long this takes after after starting a new game? Thanks.
