In this game our main mission is to unite humanity and aliens of the galaxy in order to stop the reapers( godlike machines that come every 50000 years and wipe out all intelligent civilizations.)
In the last part Reapers finally appeared and attacked Earth. On Mars we found a blueprint for weapon that could destroy the Reapers. We also had to deal with useless, idiotic politicians of both humans and aliens. We spend years warning them that Reapers are coming and they did not believe us. Now when the Reapers are here everyone wants us to save their ass. Typical politicians...
In this part we walked around the Citadel. There we spoke with two journalists. We also met with doctor Chakwas and told her to return to our ship Normandy. After that we met with our new assistant specialist Traynor. After that we spoke with admiral Hackett. He approved our plan of ignoring the Council and trying to speak directly with other leaders of aliens. After that we talked with our crew. Our pilot Joker hoped that the Council had prepared for Reapers in secret. Liara told us that Cerberus attacked her ship and she blew it up and escaped. We also met with our Shuttle pilot Steve Cortez. Then we spoke and boxed with James Vega. After that admiral Hackett asked us to raid a Cerberus lab and get some examples of Reaper tech.
After that we traveled to the moon near Palaven ( Turian homeworld). We were looking for turian Primarch Fedorian for a war summit. But very quickly we found out that he is dead. For a while it was unclear who is the next turian leader in line. But we met with one of our best friends Garrus again. And he joined our crew. After that Reaper creature that looked like a dragon flew by and dropped more reaper troops to the ground. We managed to defeat them all and protect turian base. After that we asked Garrus to lead us to the place where he last saw a new Primarch. We found general Primarch Victus and told him that he is the new leader of turians and that we need him to represent turians in our war summit. Victus promised us to help us protect Earth if we will first lessen danger to Palaven...To do that we will have to forge another unlikely Alliance- We need the krogans to join us.
Back on the Normandy something was wrong. It seemed like part of the ship was set on fire. We went to check it. It turned out that our ship's AI EDI took over the Cerberus robot's DR. Eva's body. This way EDI became our new companion. After that we spoke with Garrus and he explained how he became turian expert of fighting the Reapers. Then specialist Traynor told us that we should investigate Grissom Academy.
