Just in case, anyone wasn't aware or hadn't gotten their [url=https://www.bungie.net/en/Armory/Detail?type=item&item=3012398149&itemname=Sleeper%20Simulant]Sleeper Simulant[/url] yet; as long as you have collected 4 DVALIN Fusion Rifle Relics on your character [i](the purple items found randomly on planets with names like: "[b]DVALIN - RAS8711-FR002[/b]")[/i] you will have a new mission available to you on Earth today (and only on the 7th of each month) called "[b]The First Firewall[/b]". This is the first step for the mission chain (doesn't show up as a quest) that will end with you getting a sweet Heavy Fusion rifle that melts bosses like nobody's business. (Two crit hits from this will stagger the newest end boss) Anyways, for complete how-to (SPOILERS) check out this link: [url=http://http://www.primagames.com/games/destiny/walkthrough/destiny-taken-king-get-sleeper-simulant-exotic-fusion-rifle]Get the Sleeper Simulant Exotic Fusion Rifle[/url] It's a fair bit of work to get it but, in my honest opinion, well worth getting at least one. Good luck!
