Eidos Montreal's Secret 'AAAA' Game in Unreal Engine 5: Everything We Know So Far (2026)

Get ready, gamers! Eidos Montreal, the studio behind the Deus Ex series, is secretly cooking up a massive new game, and it's aiming for the stars – or, rather, the 'AAAA' category. A recent discovery from a LinkedIn profile of an Eidos Montreal employee has revealed that the studio is hard at work on an unannounced project, built using the cutting-edge Unreal Engine 5. This information was brought to light by the keen eye of LinkedIn scouter Timur222, who shared the news on X, further confirming whispers about the project.

But what exactly does 'AAAA' mean? It's a term used in the gaming world to describe titles with budgets and ambitions that rival the biggest blockbusters, even surpassing the more common 'AAA' designation. Think of it as the gaming equivalent of a Hollywood mega-production! This project, codenamed P11, has been in development since roughly 2019 and has reportedly soaked up hundreds of millions of dollars in investment.

In December 2025, there was information about the layoffs at Eidos Montreal, which were linked to project P11. As it nears its beta phase and eventual launch, the team has had to make some tough decisions, including reducing its headcount. But here's where it gets controversial... Sources suggest that P11 is an open-world action-adventure game played from a third-person perspective. The Insider Gaming podcast even mentioned this.

And this is the part most people miss... The game's existence came to light because of a book about cancelled video games. The project bears a striking resemblance to WiLD, a survival game that was in development by Wild Sheet Studio. This led to speculation that Eidos Montreal / Embracer had acquired the IP, but it appears that P11 is a completely new creation, albeit with some familiar elements.

When will we finally see this mysterious game? It is believed that the game will be ready to be shown later this year if things go well.

What are your thoughts on this new IP from Eidos Montreal? Do you think the 'AAAA' ambition will pay off? Share your opinions in the comments, and join the official Insider Gaming Discord server.
