GameStop tweeted out this image the other day, revealing 2 more items in their upcoming Mystery Box.
From Gears of War 4, a JD Fenix Pocket POP! Keychain & Swarm Sniper POP! will join the Titanfall 2 Atlus with Pilot in these boxes. Still no word on if these will all come together, or as separate items, or if there will be any chase figures involved. These are due on October 22.
