4LOOP release – What you need to know about the sci-fi co-op shooter from Left 4 Dead’s creator

This article contains officially confirmed information combined with expert industry speculation, rumors, and analysis. We will update this page with the latest news as soon as it’s available.

Mike Booth, the mind behind the much-loved Left 4 Dead, is back. This time, Booth is teaming up with Bad Robot Games and Sony Interactive Entertainment to bring us 4LOOP. It promises stacks of cooperative fun, as four players team up to save Earth from an invading alien force in run-based matches.

There are open playtests on the way. However, in the meantime, we know quite a bit about the game despite its relatively recent announcement. We’ll walk you through everything you need to know about Sony and Bad Robot’s brand-new co-op shooter, 4LOOP.

✓ VideoGamer Summary

• 4LOOP is an upcoming co-op shooter from Bad Robot Games and Sony Interactive Entertainment.
• The game has no confirmed release date, but it is penciled in for release on PS5 and Steam.
• The game is led by Mike Booth, the creator of Left 4 Dead.

Predicted 4LOOP release window

As of writing, 4LOOP doesn’t have a confirmed release date or release window. A rather vague “coming soon” on the game’s official Steam page is the only hint we have. Coupled with talk of internal playtests in an interview with Bad Robot Games CCO, Mike Booth, we assess that development is progressing well. We speculate that a release in late 2026 or 2027 is a reasonable estimate. That said, take this with a pinch of salt until we hear more from SIE and Bad Robot.

4LOOP gameplay and story predictions

4LOOP is described as a tactical four-player co-op shooter set in an original sci-fi universe. You squad up with three other players and drop into runs loosely inspired by rogue-likes. The primary objective, as Mike Booth explains, is to disrupt the aliens’ global mining operation to summon the Mothership and then destroy it. Success leads to weapon and equipment improvements. 

Runs are broken down into three acts, culminating in a fight against the Mothership. To succeed in each of the first two acts, you’ll need to extract at an Escape Zone, hinting at 4LOOP borrowing elements from the extraction shooter genre. Bad Robot aims to give players significant scope for experimentation and improvisation by balancing risk and reward through equipment combinations, creative ways to take down enemies, and clever cooperation with teammates.

4LOOP trailers

SIE and Bad Robot Games have released one trailer so far, an announcement trailer at The Game Awards 2025. A mix of gameplay captured on PS5 Pro and pre-rendered cinematics, it reveals that Earth was invaded by an alien force, its inhabitants crystallized into translucent, violet statues in under a minute. Only a small group survived. They must use the very machine that broke the world to save it. 

The trailer then lines up some curated gameplay clips before showcasing a machine that more-or-less 3D prints new humans, offering up an in-universe justification for the game’s match-based runs. “Fail. To save the world,” as the game’s tagline explains. 

We then get a glimpse of what looks like a meta-progress skill tree, presumably designed to make subsequent runs a little easier. We then see a team of four combatants fight a massive, airborne cube, gun down robots, and move tactically across a suburban area.

4LOOP platforms

As confirmed on the title screen at the end of the announcement trailer that debuted at The Game Awards 2025, 4LOOP will launch on PS5 and PC via Steam. As is customary for Sony-backed third-party releases, it’s doubtful the game will make its way onto Xbox or Nintendo consoles. That’s unless the game is a massive success, and even then, we’re looking at a year or two before they could theoretically land on other platforms.
