About Back 4 Blood
Back 4 Blood is a 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, once-human hosts of a deadly parasite that have turned into terrifying creatures bent on devouring 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.
The game features a dynamic 4-player co-op campaign where you must work together to survive increasingly challenging missions. Play with up to 3 friends online or go solo and lead your team in battle. Choose from 8 customizable Cleaners, each with unique abilities, and a range of lethal weapons and items. Strategize against an ever-evolving enemy that adapts to your actions.
In addition to the cooperative campaign, Back 4 Blood offers competitive multiplayer modes. Play with or against friends in PVP. Become a Cleaner with special perks or switch sides and play as the horrific Ridden. Both sides come with unique weapons, abilities, and specialties, providing a fresh and challenging experience.
A new 'roguelike' card system creates extreme replayability, putting you in control to craft custom decks, roll different builds, and undertake more demanding fights. The Dynamic Game Director constantly adjusts to player actions, ensuring exciting fights, extreme gameplay diversity, and tougher legions of Ridden, including mutated boss types up to 20 feet tall.
This US PC Steam CD Key activates the base game on Steam for players in the United States. Ensure your Steam account is set to the US region to redeem. Back 4 Blood requires an internet connection and a Steam account. Download the game directly from Steam after activation.
