A lot of things have changed in Destiny 2, but the desire to show off has not. With legacy players getting a variety of emblems to show off, some players want to access these as quickly as possible. Thankfully, doing so is quite easy, albeit tricky.
Upon making it to the farm, jump to the middle area and find vault. There you can check out your emotes, along with change your emblem. The collector’s edition and legacy ones should be waiting as soon as you get there.
