The next game from Left 4 Dead designer Mike Booth is putting a sci-fi spin on his last game's co-op action, based on a trailer Booth and producer JJ Abrams shared at The Game Awards 2025. The new game is called 4:LOOP, and it's the first project entirely developed by Bad Robot Games , film production company Bad Robot's game studio.
4:LOOP combines the four-player co-op action of Left 4 Dead, with roguelike elements enabled by what seems like a time loop mechanic. Based on the trailer, players fight a mixture of aliens and robots in each mission, all in the hopes of eventually drawing the attention of an alien mothership and destroying it.
"Each time the four-player team succeeds in a mission, they make choices to improve their equipment, building out a unique kit to survive the epic boss battle at the end of the Act," Booth said in an interview with PlayStation Blog . "If the team completes all three Acts, they defeat the Mothership and save the world. All of this is, of course, easier said than done."
