**River of Blood**, codenamed *Riverboat*, is Back 4 Blood's third and final expansion of the Annual Pass that has been released on December 6, 2022.

It features an all-new campaign act, a new Mutation family dubbed **Sentinel**, one new Cleaner, one friendly Ally, eight exclusive character skins, twelve new weapon skins, new cards, weapons, accessories and more.

All playable content included in the River of Blood expansion is accessible by all players in a party as long as one player in that party has purchased the expansion.

## New Campaign Story: Act 6

*Main article: Campaign*

This expansion expands the Campaign with a sixth Act, which consists of one Chapter and five Missions.
This will expand the Campaign to a total of 6 Acts, 12 Chapters and 44 Missions.

Players who either own the expansion themselves or have at least one player on their team who has purchased this content can jump into this Act.
Furthermore, players do not need to have completed any of the previous Acts to be able to enter Act 6. Only the restrictions mentioned above are in effect.

As the Ridden Hives in the Tunnels of Terror and Act 5 from the Children of the Worm expansions were already excluded from matchmaking via Quickplay, this rule is expected to also apply to Act 6, as this content is tied to the respective expansion.

Duffel Bags are also available in Act 6.

The sixth Act includes the following Missions:
