Some missions are not available for lore reasons depending on player choices and whether Leviathan DLC is installed. All assignments are journaled so you won't miss them.

1. N7 Extractions - head back to Earth for a quick jaunt to recover N7 soldiers from the Villa in Brazil

2. Bekenstein: Negotiation - press the flesh to persuade the recalcitrant colony and its politicians to back the war effort.

3. Phoenix Project - escort a news crew to the site of Cerberus experiments to see whether you can blacken their name and encourage defectors

4. Veterans v Criminals * - 2 forces on the opposite sides of the galaxy need to be extracted, one is needed by Aria help take Omega, the other is led by an old friend of Garrus. There is only time to save one.

5. Strontium Mule - a merchant ship was used by Cerberus to deploy forces during the coup. A reward is available, dead or alive, for the captain.

6. Aite * - return to the Overlord facility which Cerberus is using to produce AI like Eva Coré. (Upgrade to rewards if Overlord was not shut down).

7. Find the Rachni * - see if you can find the Rachni's new home hidden in the map to deliver a QEC and allow their forces to join with the Allies.

8. Batarian Attack - Batarian forces are keen to stop Cannibal production on Camala. They want Alliance support. Do you trust them?

9. Aria's Forces - help Aria assemble a force with the ability to take back Omega. (Outcome of this mission affects the amount of forces that are killed during the fight to retake Omega)

10. Collector Cruiser - the Geth/Quarians have disabled a ship. A N7 unit with the leviathan weapon went in, but all has gone silent. Deploy a team to find out what happened.

11. Minuteman Station - Cerberus' largest station has been found and needs to be taken out. Outcome is dependent on completions in anti-cerberus missions across all 3 games, whether player choices have supported or been against cerberus and whether the player has access to intelligence on cerberus gathered in ME1/2/3. Rewards for the best outcome are a large amount of equipment war assets including Atlas mechs, Hammerheads and a Normandy class flotilla. But beware - Cerberus has nasty surprises for those who do not fully prepare.

12. The Evacuation of Thessia - with the Asari matriarchy stuck on Thessia, their military is in disarray and desperate. They want to head back to their home planet and evacuate as many as possible. Decide whether to support them, and then head back and undertake a rescue. Once arrived choose who to save and who to leave behind, and how long to remain in system as the fleets have to hold back the Reapers.
