Destiny Emblem Collector is the most complete source for Destiny emblems: what they look like, exactly how to get them, and whether they're still available.
DEC currently tracks 1019 Destiny 2 emblems and 271 Destiny 1 emblems.
There are a few different places to get updates/patch notes from DEC and emblem news. All of these different places should have the same info posted to them, so follow wherever you spend your time!
Marathon Emblem Collector is currently in beta! Come over and help test, see all the cool emblems, and help gather info!
There's a lot of stuff still under development (and Marathon doesn't have an API), so please pardon our dust!
Bungie has announced that Destiny 2 will no longer receive updates after June 9th, 2026.
However, DEC will still continue to run for the forseeable future! I have no plans to retire the site, though parts of the site will change due to no new content being released.
Keep an eye out here for any new updates as they happen!
