Tali’Zorah is one of Shepard’s most loyal companions and is an extremely important existence throughout the Mass Effect trilogy. During their first meeting, she will help expose Saren as a traitor and this will make Shepard the first human Specter.
As the story goes, before the events of the first Mass Effect, Tali will be on her quarian pilgrimage. There she uncovers audio evidence of Saren’s involvement in the attack on Eden Prime and she then wishes to trade the information to the Shadow Broker for protection from Saren’s minions.
The rescue mission includes Shepard find and rescue Tali from assassins after she is double-crossed by Fist, the owner of Chora’s Den who works for Saren. This mission has to be complete and with a 100% success rate at that because Tali is a mandatory squadmate, so to continue the plot she has to be protected.
First players need to recruit Garrus Vakarian, Urdnot Wrex, or both for a lead about reaching Fist. After Shepard has dealt with Fist, they will learn he has double-crossed Tali but they will only have a limited amount of time to reach her before the assassin’s attack.
Though the mission in itself isn’t that hard to complete, the time limit, however, makes the mission seem more stressful and urgent. So, here’s how to rescue and recruit Tali’Zorah Nar Rayya in Mass Effect.
After dealing with the fist, the players will get a 4-minute countdown, during which Shepard and their squad need to fight their way back out of Chora’s Den, as more thugs and enemies arrive. However, it’s also possible to cheese this fight and run straight through the club to the exit while avoiding enemy fire. but it’s better not to take such a gamble.
The easiest route is to go down the ramp and exit the alcove, then turn right and go up the stairs and through the door. In the alley behind the Markets, go up the stairs again and keep going straight to trigger the cutscene.
Remember that should you fail to reach Tali on time, then players will receive a critical mission failure and will be forced to start over. Shepard will need to help Tali fight off the assassins and as thanks for saving her, she presents her evidence against Saren to Udina and Anderson, then to the Council. She is a critical and loyal member of Shepard’s squad for the entire trilogy, so better save her earnestly
