About the Game
Back 4 Blood is a thrilling cooperative first-person shooter from the creators of the critically acclaimed Left 4 Dead franchise. You are at the center of a war against the Ridden. These once-human hosts of a deadly parasite have turned into terrifying creatures bent on devouring what remains of civilization. With humanity's extinction on the line, it's up to you and your friends to take the fight to the enemy, eradicate the Ridden, and reclaim the world.
Fight your way through a dynamic, perilous world in a 4-player co-op story campaign where you must work together to survive increasingly challenging missions. Play with up to 3 of your friends online or go solo and lead your team in battle.
Choose from 8 customizable Cleaners, one of the immune survivors, and a range of lethal weapons and items. Strategise against an ever-evolving enemy bent on your total destruction.
Play with or against friends in PVP. Switch between playing as a Cleaner with special perks and the horrific Ridden. Both sides come with unique weapons, abilities, and specialties.
A new "rogue-lite" Card System creates different experiences each and every time, putting you in control to craft custom decks, roll different builds and undertake more demanding fights.
The Game Director is constantly adjusting to player actions, ensuring exciting fights, extreme gameplay diversity, and tougher legions of Ridden - including mutated boss types up to 20 feet tall.

BUG FIXES
- Duffel Bags
- Added item highlight function to Duffel Bags when a player is nearby.
- Duffel Bags now count as Utility items, so if a player has disabled or replaced item slots, they can still pick up a Duffel Bag.
- Developer Note - With this change, only the Utility slot Duffel Bag will spawn. This does not impact the reward items redeemed at the end of the level.
- Offline
- Fixed an issue where Duffel Bags were not always spawning in Offline Mode.
- Reward Items
- Duffel Bags now only contain Expansion 2 cards and Expansion 2 character skins. When a player has all this content unlocked, the Duffel Bag will grant Burn Cards.
- Other Expansion 2 non-exclusive cosmetic content (weapon skins, emblems/sprays/banners) are available to unlock with Supply Points through Roving Merchant supply lines.
- Developer Note - This is a temporary fix implemented to ensure that players are able to unlock the Expansion 2 cards as they encounter duffel bags. We are working on a more permanent solution at this time.

[November 11 2021 - 10:30 AM PT] Developer Update - Thanks to your help, we have identified an issue related to Specials spawning and suspect their spawn cards are being repeated unintentionally. We are actively investigating and working on a fix. Thank you for your patience.
Developer Update - We wanted to highlight the following bug fix with some additional information: "Fixed some issues related to Specials spawning." We found an issue where Specials would frequently duplicate their spawn cards, compounding as players progressed through levels. This would often result in an unfair amount of Specials overwhelming Cleaner teams. In future patches, we are going to continue to dig into spawning issues to help further smooth out the experience.
The November 2021 Update brings quality of life updates, along with balance updates for Campaign and Swarm PvP!
