The Creator of Left 4 Dead Reveals New Co-Op Action Game 4:Loop
A new PlayStation 5 exclusive co-op game has been revealed at The Game Awards, called 4:Loop. The new co-op title 4:Loop comes directly from the creator of Left 4 Dead, one of the most popular four-player co-op action games ever, and gamers who have been watching The Game Awards are intrigued.
Although the original Left 4 Dead released in 2008 and its sequel a mere year later, the game has remained a popular title among gamers nonetheless. In Left 4 Dead, players form a four-member team who have to survive a number of stages in a 28 Days Later-like zombie-infested world. The combination of gunplay, cooperation, interesting characters, and the AI Director, which chooses the most inopportune times to spawn enemies, have helped the game to remain fairly popular, with Left 4 Dead 2 still managing to hold onto an average of over 30,000 active players daily for nearly the entirety of 2025.

Left 4 Dead Designer and Creator Returns with a New 4-Player Co-Op Game
During The Game Awards, a new game called 4:Loop from Sony Interactive Entertainment and Bad Robot Games was announced. The game is being brought to life by Mike Booth, the original creator and lead designer of Left 4 Dead, and the creator of the AI Director. Unlike Left 4 Dead, the game is set in a unique sci-fi world, but like Left 4 Dead, players can expect a four-person cooperative shooter that will require cooperation in order to survive. However, surviving isn’t necessarily the path to victory here, with the game sporting a catchphrase of “Fail. To save the world.”
The story of the four-person cooperative game isn’t completely explained yet, but something has gone wrong with new technology, and the entire population of the planet has been lost in an alien invasion. NPCs are shown trapped in mid-motion, and the narrator explains that it took mere moments for everything to be lost. Players will be making use of the technology responsible for destroying the world in order to save it, and player death is part of the equation.
In Left 4 Dead, if all four players died, the story is canonically over, and players have to start over and try again from the most recent continuation point. However, in 4:Loop, losing is part of the plot. The narrator of the trailer explains that the four-player strike team is up against impossible odds, but it’s taken that into consideration, with a system that rebuilds the defeated character so they can try again with what they’ve learned. The trailer shows the player characters being rebuilt over and over again, which will carry on for as long as it takes to win. From the look of the trailer, players will build up their characters with a skilltree that carries over between regenerations.
Mike Booth revealed a bit more about what players can expect from the game in a talk with PlayStation. He explained that in the time since Left 4 Dead‘s original development, players have become accustomed to cooperative mechanics like saving teammates from creatures that can incap or disable, allowing them to push the boundaries of 4:Loop even further. Players will be able to improvise, with a less linear path, and can even carry downed friends if the need strikes. The game’s roguelike mechanics have been designed to be as frictionless as possible, so that players don’t have to waste time developing a character every time they hop into the game or lose.
The ultimate goal for the team is to draw the attention of the alien Mothership, put a stop to its mining operation on Earth, and then destroy it. Players build up their kit and equipment at the end of each mission, with three total Acts to get through to defeat the Mothership. However, judging from the emphasis on failing and retrying roguelike mechanics, it doesn’t seem as though it will be an easy or quick task.
This is the first Left 4 Dead-like game to come directly from the creator of the original title. While Left 4 Dead has had spiritual successors, like Back 4 Blood, which was created by the game’s original studio Turtle Rock, Booth wasn’t involved, as he left the company in 2012. Back 4 Blood unfortunately disappointed players on arrival, while Turtle Rock’s 4v1 game Evolve initially performed well, but ultimately saw its servers shut down three years after its launch. Whether Mike Booth’s game can bring back the core mechanics and fun that players came to love about Left 4 Dead remains to be seen, but with playtests arriving in the months to come, it won’t take long before players can find out more.
