Back 4 Blood has amassed over 6 million players since its launch.

Back 4 Blood is an example of the Game Pass effect at work.

Back 4 Blood developer Turtle Rock Studios has announced that the game has already reached the 6 million player milestone just two weeks after launch. The developer announced the news via the official Back 4 Blood Twitter account today, thanking “Cleaners” for their hard work and dedication over the past fifteen days.

While Back 4 Blood has had a pretty positive and successful release, these numbers are most likely a result of the game being on Xbox Game Pass. Microsoft announced earlier in the month that Back 4 Blood would be coming to the service on launch day, possibly prompting quite a few people to try the game through Game Pass rather than pre-order or purchase it.

This is not to say that Back 4 Blood would not have been successful without Game Pass. People have been clamoring for a true successor to the Left 4 Dead franchise for a while now, and Back 4 Blood debuted quite well on the UK box charts, ranking fourth behind high-profile titles like Metroid Dread. , FIFA 22, and Far Cry 6.

Even if a good amount of those 6 million players are currently inactive due to having tried it once via Game Pass, Back 4 Blood still has a dedicated audience that loves the game. However, several players are getting nervous about the game’s solo player mode. Back 4 Blood disables progression for solo players, forcing them to play matches with random teammates to earn Supply Points.

Thanks for all your hard work, Cleaners! With this many Cleaners on our side, we’ll stop the Ridden in no time. #Back4Blood pic.twitter.com/quA8A4hWNo

Turtle Rock has let fans know that it is working on a fix, though more than two weeks later, fans are starting to get impatient. Even in responses to Back 4 Blood’s celebratory tweet, there are a number of players still wondering if improvements are coming to the game’s solo mode or not. Hopefully Turtle Rock can implement something sooner rather than later.

If you’d like to see Back 4 Blood for yourself, the game is currently available for PC, PS4, PS5, Xbox One, and Xbox Series X.
