The Black Market, the cosmetic marketplace for Call of Duty, is now live in Call of Duty: Black Ops 4 on PlayStation 4 and will be live on PC and Xbox One on Oct. 26, developer Treyarch announced on Friday morning.

At launch, the only Black Market feature that is turned on is the Contraband stream, a progression system that allows players to unlock new cosmetic content — such as new Blackout characters, weapon skins, specialist outfits, tags and gestures — simply by playing the game. Much like Fortnite’s Battle Pass, the Contraband stream will award players loot for earning in-game experience. Each new set of unlocks will be called an Operation and will rotate on a seasonal basis, with new rewards every few months.

The Black Market will also feature special events that only stick around for a short time. The first of these events will begin Oct. 20 for PS4 players — with other platforms following a week later — and will feature special Halloween-themed unlocks. These will only be available for a short time, but there will be more events in the future, according to Treyarch.

The final addition to the game’s Black Market is Blackjack’s Shop. Here, players will be able to purchase specific cosmetic pieces that will only be available for a week at a time. Blackjack’s Shop will go live in Black Ops 4 sometime in November.
