Destiny 2 has continuously evolved, much more so after the release of Forsaken and Bungie's very public breakup with Activision. The Tribute Hall, home of the Leviathan Raid, is a specific area that hides secrets and the gateway to sweet loot and it looks like players are still finding new tributes there.
For those that may not know, the Tribute Hall offers numerous activities for players to take part in and is a vital part of the new Bad JuJu catalyst. The tributes themselves can be bought from the Visage of Calus, though they're definitely going to cost ya unless there is a ranked up discount in place. One Destiny 2 player in particular found that the Champion Bounties-driven discount actually hides a secret tribute called Tribute 51 (come on, now) and has been nicknamed "Gotta Collect 'Em All." To unlock this, players must have the full discount in place after placing every single tribute in the hall itself.
So what's this secret tribute do? We can't really tell. At face value, it makes the door symmetrical, but no boon has been seen thus far. Given that a full discount isn't supposed to be possible, it's probable that this is a glitch, or that the effect of this particular tribute hasn't gone live in the game itself yet.
Or it could just be there to be pretty, who knows?
Aside from the secret Destiny 2 Tribute Hall tribute, the game itself is live now on Xbox One, PlayStation 4, and PC with Shadowkeep kicking off Year 3 on September 3rd.
