Call of Duty: Black Ops 4 is quickly approaching, and as Activision previously revealed, it'll feature an extensive amount of content right from the outset, including the new battle royale-style Blackout mode and three Zombies episodes. That certainly isn't all; Activision says developer Treyarch will continue to support the game with a regular stream of free post-release content, a taste of which the publisher has now revealed.

In a post on PlayStation Blog, Activision gave fans their first look at some of the new content coming to the game shortly after it launches. As with previous Call of Duty titles, all of this will arrive first on PS4 as part of Activision's ongoing exclusivity agreement with Sony. The publisher hasn't stated how long the PS4 exclusivity period will be for Black Ops 4's DLC, but content for previous Call of Duty games would arrive on Xbox One and PC about a month after it debuted on Sony's console.
