Bungie’s first event for Destiny 2, namely the Faction Rally, will be coming to an end on October 3rd, 2 AM PST when the weekly reset is complete. You can still continue completing activities and earning Tokens for rank-up packages but there isn’t much time left.
It’s also worth noting that except for Future War Cult, the factions will only offer gear and weapons in rank-up packages for the first 30 Engrams. After this, you receive nothing but shaders. Future War Cult seems to be bugged in that it offers weapons and gear even after the first 30 Engrams are decoded.
Whichever faction earns the most rank-up packages during the event will be dubbed the “winner” and their featured weapon will be available to all. If you pledged allegiance to the winning faction, said weapon is available for 1000 Glimmer. Everyone else needs to pay 50,000 Glimmer for it.
We don’t know about the schedule for when the Faction Rally returns but Bungie did note that it will be in the “near future”. So keep your eyes and ears peeled.
