Jia Jem Wearing Costume From Mass Effect 2

Shepard departs with the recruited members on a shuttle towards their next mission as the Normandy prepares the IFF for testing. However, after the IFF is activated, it emits a tracking signal and the Collectors are able to locate and board the Normandy. Joker is forced to give control of the ship to EDI - a potentially dangerous move. Gaining control of the ship, EDI pilots the Normandy away from the Collectors and rids the ship of all enemies, but the entire crew barring Joker is taken by the Collectors. Shepard's hand is forced - Shepard can either complete secondary missions and sacrifice the Normandy's crew, or immediately go through the Omega-4 relay to rescue them.
After traveling through the relay, the game may proceed in different ways. Depending on whether Shepard enters the Omega-4 relay quickly, has upgraded parts of the Normandy, and has earned the loyalty of team members, any combination of crew and team may survive the final mission, which ultimately influences Shepard's fate. After entering the relay, the Normandy enters a massive debris field littered with the wrecks of ancient starships that tried to navigate the Omega-4 relay. After a fight with the debris field's automated defenses, the Normandy encounters and ultimately destroys the Collector cruiser. The shockwave from the explosion, disables the Normandy and forces the ship to crash land on the Collector station. After boarding the station, Shepard and the team fight their way towards the center of the base eventually encountering the Normandy crew and the abducted human colonists. If Shepard delayed entering the Omega-4 relay, the Normandy crew will be harvested by the Collectors and Shepard will only manage to save a few of the human colonists. After rescuing the colonists and crew, Shepard continues to proceed to the large central chamber in the middle of the base and discovers that the Collectors have been constructing a new Reaper, made from the genetic material of the abducted humans and fused with the advanced technology of the Reapers. EDI postulates that the Reapers may be facilitating the Reaper equivalent of reproduction but remains unsure as to the Reapers' true motives. Shepard targets the weak points of the machine, which is in the early stages of construction, and it falls deep into the station core.
