Destiny's raids have been recognised as the highlight of the series ever since the original's Vault of Glass, since when they've only got more ambitious in terms of intricacy, and the secrets they conceal. But the sequel's Leviathan sets new standards in these fields. Here are some cool things we found on our first run.

For the best tips and strategies to beat the raid itself, check out our Destiny 2 Leviathan raid guide.

The biggest secret is the existence of a network of Tunnels, which weave and wrap around all of the raid’s arenas. You’ve noticed all those locked doors? Guess where they lead. Some can be opened from within the arenas, via inconspicuous switches, but all can be opened from the tunnels, which means you can access parts of the raid before they’re active. We got to Calus’s throne room while still on the Pleasure Gardens, for instance.
