Return of the Loot.
When Destiny originally launched, there was a famous exploit that undermined the grind entirely, and allowed for players to stockpile on items and drops pretty easily- it was then loot cave glitch, which allowed players to obtain a large stash of glimmer, Engrams, and other nice loot drops quickly by killing infinitely-spawning enemies.
These loot caves were quickly patched out, of course, but a brand new video may have shown how to access a new one on Venus. The best part about this loot cave is that the enemies that appear are not just infinitely respawning, but also easy to kill, meaning it’s stupidly easy to stock up on all sorts of goodies by abusing the loot cave.
If you do want to use this loot cave, you might want to get on with it, since now it is in the wild, it is likely that Bungie will catch wind of it soon and patch it out.
