GM this week: The Arms Dealer
The Arms Dealer is the Grandmaster Vanguard Alert for October 6 to October 13, 2026. It leaves at Tuesday reset, 17:00 UTC, on October 13. The strike is on the EDZ. The featured weapon is Ouster Engine, a grenade launcher.
Run the clear before the reset if that grenade launcher is the missing piece. The node still expects a full fireteam from orbit, and the next Alert name lands on October 13.
What the clear pays
The Arms Dealer features Ouster Engine. It is a grenade launcher, and it is the named weapon on this Alert. Enhancement materials still come with a Grandmaster clear, along with Fireteam Ops rewards scaled to your grade.
The weekly clear is the run that pays the featured weapon. Clearing the Alert on more than 1 character multiplies the material payout before October 13.

How to launch it
The weekly featured run is the Grandmaster Vanguard Alert inside Fireteam Ops. Matchmaking is off on that node. Join-in-progress is off, so the fireteam has to launch together. Open the activity preview and read the power delta before you spend a wipe in the EDZ.
Anti-champion stuns sit on weapon frames and on subclass verbs. Check the preview for the champion set on this Alert, then lock the loadout.
Skip the grind
The Arms Dealer stays up through the October 13 reset, and Ouster Engine is the grenade launcher on the card. A premade fireteam is required because matchmaking is off on the Alert node. A PRO team can clear it on your account and leave the drop in your vault.
