Want to know how many acts there are in Back 4 Blood? Back 4 Blood’s act structure differs from Left 4 Dead’s campaigns in that missions comprise chapters, chapters comprise acts, and acts comprise the whole campaign.

A typical Left 4 Dead campaign lasts just under an hour, whereas a single chapter in Back 4 Blood lasts about as long, in our experience. Since there are multiple chapters to an act, and multiple acts to the whole campaign, it looks like Back 4 Blood will be a much meatier experience. Even the length of each mission can vary significantly when you start to throw corruption cards into the mix to adjust the difficulty of the zombie game.

The spiritual successor to Left 4 Dead has already proven to be very popular, reaching just shy of 100k concurrent players during its closed beta period. Back 4 Blood was originally supposed to launch back in June, but the release date was pushed back by four months to give the developers more time to polish the game.

Back 4 Blood features eight characters at launch (we have a guide for how to unlock Jim, Karlee, Doc, and Hoffman), each with their own unique set of skills to complement any type of party. Picking the right set of characters is crucial if you want to tackle the game’s hardest difficulty mode. Here’s everything you need to know about the act system in Back 4 Blood.

The number of acts in Back 4 Blood

There are four acts in Back 4 Blood, and each one is split into chapters. Each chapter contains between one and five missions, and the final mission in each chapter acts as a finale. As a result, acts can be surprisingly lengthy; the first act alone is 13 levels long and takes several hours to complete.

Thankfully, you’re able to drop out after every chapter and preserve progress in your current run. To continue your run, go into the campaign selection and choose ‘Continue run’ option. There are currently 33 levels in the Back 4 Blood campaign, and they are as follows:
