4LOOP Announced as a New Tactical Cooperative Shooter from Left 4 Dead Creator Mike Booth
A major reveal at The Game Awards 2025 came from Left 4 Dead creator Mike Booth, who took the stage alongside JJ Abrams of Bad Robot to officially unveil 4LOOP, a new tactical cooperative shooter designed around replayability, teamwork, and creative problem solving. The reveal trailer sets the tone with an eccentric scientist explaining that players will be resurrected repeatedly as they die, pushing them to learn from failure in order to save a world overwhelmed by an alien invasion.
Players can already begin engaging with the project. 4LOOP is available to wishlist on Steam and PlayStation 5 and those eager to join development testing can sign up for upcoming sessions through the official playtest portal. Even on PC, the game will be published by Sony, underscoring the company’s continued investment in high profile cooperative experiences across platforms.
Developed by Booth and the interactive storytellers at Bad Robot Games, 4LOOP is structured as a four player tactical co op shooter built for endless replayability. The core philosophy emphasizes growth through failure. Each loop presents new opportunities to refine tactics, coordinate roles, and construct the ultimate team composition. The combination of tactical decision making and continuous iteration positions 4LOOP as a spiritual evolution of the cooperative design principles that defined Left 4 Dead while adding a strategic layer that rewards experimentation.
With Sony publishing, Bad Robot Games leading creative direction, and Mike Booth returning to co op shooter design, 4LOOP arrives with strong pedigree and high expectations. As playtesting ramps up, players will soon be able to experience firsthand how the game’s looping structure and tactical depth reshape cooperative action gameplay.
