Hey all! Here's a clear of the first Tier in The Reckoning, Season of the Drifter's PvE side of the content. It's basically like other Horde Mode-like content in Destiny; defeat enemies to progress (fill the 'Dominance' percentage to 100), then you get a big baddie to fight at the end. This matchmaking event also has modifiers... which I assume will rotate daily / weekly like elsewhere in the game. You should probably match your loadout to those modifiers to have a better chance at success. Here, I had Void Singe, Prism (rotating Singes), and Heavyweight.
Using a 'weak mote' in the pre-game area rewards you upon completion with an armor piece matching the type of mote you use (in this case, Sentry).
Pretty standard PvE, looks like. I definitely underestimated enemy strength here (650 recommended), so I imagine subsequent tiers are going to require more teamwork / higher light.
Thank you very much for watching, and I hope you enjoy the video!
