Destiny 2 - how to get the Bastion rifle

First of all, you need to complete the quest "Walk the corridors of time“Where you need to explore the Corridors of Time on Mercury and follow the sequence of corridors in the correct order.

After going through all 30 corridors, you will reach the last room. Interact with the grave to receive the Chronometric Weapon Core and complete the quest.

Step 1: talk to Saint-14

Return to Saint-14 in the Tower and talk to him to find a new quest "Remembrance".

Step 2: defeat the Fallen Captains and Minions

You will need to collect five data from Fallen Captains and Minions. The easiest way to do this is to travel to Thieves' Landing in the Tangled Shore region. After disembarking, go to the left side of the location and go up, past the lost sector "Empty barrel". Follow the road to the left until you see enemies. The Fallen Captain will always run away - kill him, head back to Thief's Landing, and then head back and repeat the process.
