Published on: Oct 7, 2015 @ 07:12 UPDATE: The “Firewall” mission is available as soon as you turn in all 4 Relics. The search for Sleeper Simulant starts with “The First Firewall” quest! To unlock it, you’ll need to turn in all four Legendary “DVALIN” Relics (which drop at random) to the Gunsmith. Update: Part 2 If you've collected the items needed to unlock it, The First Firewall is in your Director today. If you haven't, it will return in time. — Bungie (@Bungie) October 7, 2015 [divider] The First Firewall This mission pops up in the Cosmodrome, taking you to Rasputin’s Bunker where Omnigul is first spotted
