The Frontier Pass is a one-time, 20-day onboarding track for Commanders at Ops 10-19. It runs four event types on a schedule -- Extermination! (clear hostiles), Alliance Unity (alliance-wide goals), Resource Master (mining), and Foundations of Power (station and research upgrades) -- and completing them earns Frontier Pass Points toward 20 milestones. Rewards lean toward raw fleet-building resources: Latinum, Parsteel, Tritanium, Gas, Ore, Crystal, Loyalty Points, Ship Parts, Ship and Officer XP, shards of Lieutenant Picard, and Frontier Store currency. Because it's one-time, once it's gone it's gone -- you won't see it or any Battle Pass again until you cross Ops 18 (or you'll simply never see it again if you were already past that level when it fired).
This is a one-time catch-up track for returning Commanders who meet Scopely's inactivity criteria -- it starts automatically on your next login, no activation needed beyond claiming your first Daily Briefing gift. From there it unlocks a daily gift (including shards of Epic Officer Gwen DeMarco), a 14-day milestone track paying Core Progression Materials and Rare Officer Unlock Tokens, access to catch-up store offers, and a purchase-optional Heroic event called Assume Command. The free track -- Daily Briefing plus milestones -- needs no spending at all. It only runs once per account: coming back a second time after going inactive again doesn't retrigger it, and missing days mid-event costs you whatever rewards fell on those days rather than voiding the whole thing.
The Active Duty Recall Program is the alliance side of the same idea: a time-limited event (roughly four weeks, with the event store staying open a week longer) where you send a personal invite link to specific inactive players -- Level 20+, inactive 30+ days, and in your own region -- and earn Unity Coins when they return and play. There's a cap of 20 counted returns per inviter, and the invite link itself only works from a mobile device. It's a narrower, alliance-recruiting-flavored counterpart to the 14-Day Return Event above: that one pulls the returning player back in, this one rewards the ally who did the pulling.
