The Seraphim Vault was a hidden area in the Destiny beta that players found via an invisible wall – and it may still be accessible in the final game.
You can find it on Earth’s Cosmodrome level – it’s a little convoluted getting there, and there’s not a lot to do apart from explore once you find it – but it seems to be there all the same.
Reader @Zephyr_Tenno sent us these screen grabs from the PS4 version of the game, suggesting Bungie is likely to unlock the area at a later date. It might have something to do with the recently leaked missions that popped up over the weekend.
The Seraphim Vault was first discovered in the Destiny beta back in July. Entry in the final game requires the same method, so you’ll need a little patience to find it.
I just tried to check it out but I’m unable to sign in to Destiny’s servers…
