Kasumi needs to join the war effort after Citadel: Hanar Diplomat to be available. Javik is available from the moment you opened his pod on Priority: Eden Prime. Jack needs to be rescued in Grissom Academy: Emergency Evacuation and then met in Purgatory to be available. Jacob is available after meeting him on Huerta Memorial Hospital provided he was rescued in Arrae: Ex-Cerberus Scientists. Grunt will be available if he returned to Shepard after wrestling some rachni in Attican Traverse: Krogan Team. Garrus just needs to survive the suicide mission to be available.
Only surviving full squadmates from all three games can be invited in provided their Mass Effect 3 story arcs have been completed.Ĭuriously, none of the other Normandy shipmates past or present may be invited in: Rupert Gardner, Diana Allers, Karin Chakwas/ Chloe Michel, Kelly Chambers, Greg Adams, Kenneth Donnelly and Gabriella Daniels are all absent so don't bother looking for prerequisites. Everyone else, including present ME3 squadmates not yet mentioned, are optional invites. The bare minimum of people whose survival from the first two games are assured are auto-invited: Joker, EDI, Liara, James Vega, Steve Cortez, and Samantha Traynor.
