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.”
Sony Interactive Entertainment announced that it would be publishing 4:LOOP earlier in December, so naturally the game will be available on PS5 and PC when it launches. Players interested in trying 4:LOOP can sign up on the game’s website.
