Back 4 Blood, the newly released PC and console shooter from the developers of Left 4 Dead, is getting a good amount of post-launch DLC, and the studio has now run through what's coming.

The post-launch content roadmap includes free updates and releases that are part of the paid-for annual pass. The free updates include a solo offline mode--which players had been requesting since launch--as well as a new difficulty level, another co-op mode, new cards and a new card type, and seasonal content for the holidays.

As for the paid content, the Tunnels of Terror expansion is coming in 2022. It features new story content, another activity type, and more weapons, cards, and skins. More details about Tunnels of Terror will be announced later. It's the first of three expansions included in the Annual Pass, which costs $40 or is available through the Back 4 Blood Deluxe ($90) and Ultimate ($100) editions.
