Hidden within the Heroic version of the Zero Hour mission is a datapad that can be collected, unlocking a Bounty called "Void Configuration". This bounty appears to be 1 of several steps needed to acquire a new Exotic Ship. The Heroic mission has a void-burn modifier. The popular assumption is that this modifier will rotate weekly, just like the elemental burns for the heroic Whisper of the Worm mission rotated. So the going theory is that this week, we have access to the Void Configuration bounty, and then next week and the week after we'll be able to complete Arc and Solar versions.

To complete the Void Configuration Bounty, you must find 3 keycards hidden throughout the mission, and also collect Siva Particulates (which are awarded by finishing the Zero Hour mission on the Heroic difficulty).

* NOTE: The Siva Particulates are only awarded after your first heroic completion of the week... this means that if you've already completed the heroic mission this week, you won't be able to complete this bounty. You'll have to wait until the next time a Void week comes around, and complete it then. *

* NOTE 2: THIS BOUNTY IS CURRENTLY BUGGED. IT WILL SOMETIMES VANISH FROM YOUR INVENTORY. TO PREVENT THIS, CLOSE ANY COMPANION APPS OR 3RD-PARTY DESTINY APPS WHILE PLAYING THIS MISSION *

Here is a video guide showing the locations of the datapad and the 3 hidden keycards:

The Cryptarch Puzzle

This is where things get wild. There is another step tied to this bounty, which involves using some computer terminals inside the Vault (near the end of the mission) to solve a puzzle. I'd be lying if I claimed to understand it... but here is a guide for anyone interested in tackling it.

For reference when doing the Heroic mission:

Here is the path through the “burning floor” section of the vault during the heroic Zero Hour mission:

Vs Calus (seriously... 1 plate?!)

Vs Riven

Vs Insurrection Prime
