Polish publisher All in! Games has been keeping a pretty big secret. According to an exclusive report from Need4Games published on November 12, 2025, the company has been quietly developing an open world game based on a world-renowned IP for the past four years. The project, codenamed Project Rainbow, is coming to PC and consoles, though exactly which massive franchise it’s connected to remains a mystery that’s driving speculation into overdrive.
Who Is All In Games?
Before diving into the speculation, it’s worth understanding who All in! Games actually is and what they’re known for. The Polish company operates as a creative hub focused on investments in video game production through in-house studios. They’re not a massive AAA publisher like EA or Ubisoft, but they’ve built a respectable portfolio of games across multiple platforms. Their business model centers on partnering with developers to bring unique gaming experiences to market while handling publishing, marketing, and distribution.
All in! Games has published titles like Ghostrunner (a cyberpunk parkour action game), Chernobylite (a survival horror RPG), and Tools Up (a couch co-op game). These aren’t household names that dominate sales charts, but they’re quality mid-tier releases that found their audiences. The fact that they’re now working on something based on a world-renowned IP represents a significant step up in ambition and scale for the publisher.
Project Rainbow Details
According to Need4Games’ exclusive report, Project Rainbow entered development in 2021, making it a four-year project as of November 2025. That’s a substantial development timeline, especially for a publisher that typically works on smaller-scale titles. Four years suggests this is a proper AAA-level production with the budget, team size, and technical ambition to match. You don’t spend four years on a game unless you’re building something significant.
The game is described as open world, which immediately puts it in conversation with major franchises and raises questions about which IP All in! Games secured. Open world games require massive resources, extensive playtesting, and sophisticated technical infrastructure to pull off successfully. The fact that a mid-tier publisher is attempting this format with a licensed IP suggests they’ve got serious financial backing and confidence in the project.
The IP Guessing Game
The most tantalizing part of this leak is the reference to a world-renowned IP. That phrase narrows things down considerably. We’re not talking about a moderately popular franchise or a cult classic. World-renowned means globally recognized, massively popular, and likely tied to other media beyond just games. So what could it be?
Given All in! Games’ Polish roots, some are speculating about The Witcher. However, that seems unlikely since CD Projekt Red controls that IP fiercely and is actively developing their own Witcher projects. Other guesses include Middle-earth (Lord of the Rings), which has been licensed for numerous games over the years, or potentially Warhammer, which has seen a recent resurgence in gaming adaptations. The Harry Potter universe is another possibility, especially following Hogwarts Legacy’s massive success proving there’s demand for open world games set in that world.
The Rainbow Connection
The codename Project Rainbow might offer a clue. In game development, project codenames sometimes relate thematically to the actual IP, though this isn’t always the case. Rainbow could reference something colorful, diverse, or connected to weather and nature. It could also be completely arbitrary, chosen to avoid giving away the actual IP during internal development conversations.
One interesting angle is Rainbow Six, Ubisoft’s tactical shooter franchise. However, that franchise isn’t typically associated with open world gameplay, and Ubisoft closely guards its own IPs. Still, stranger licensing deals have happened in the industry, and an open world Rainbow Six tactical game could be an intriguing twist on the formula.
PC and Console Release
Project Rainbow is confirmed for PC and consoles, which in 2025 typically means PlayStation 5, Xbox Series X/S, and potentially Nintendo Switch 2 if that console launches in the expected 2025-2026 timeframe. Cross-generational releases to PS4 and Xbox One seem unlikely given the project’s 2021 start date and the industry’s shift away from last-gen hardware.
Launching on multiple platforms simultaneously is crucial for a licensed IP game. The broader the reach, the more potential customers you can convert, and the more valuable the license becomes. All in! Games needs this project to succeed commercially to justify the development costs and licensing fees associated with a world-renowned IP. A multi-platform strategy maximizes those chances.
When Can We Expect It?
With four years of development already invested and the project still apparently under wraps, a 2026 or 2027 release window seems most realistic. Major open world games typically need at least four to six years from concept to launch, sometimes longer. If All in! Games started in 2021 and we’re now in late 2025, they’re potentially in the final stretch of production, which means marketing, trailers, and official announcements could start happening in the next 6-12 months.
The lack of any official announcement yet suggests either the project is still rough around the edges and not ready to show, or All in! Games and the IP holder are planning a major reveal at a significant gaming event. E3 is dead, but Summer Game Fest, The Game Awards, and various publisher-specific showcases offer plenty of venues for a big reveal. Given the world-renowned IP angle, they’d want maximum eyeballs when they finally pull back the curtain.
The Risk and Reward
Taking on a world-renowned IP is a double-edged sword. On one hand, you get instant brand recognition, an existing fanbase, and built-in marketing through the IP’s established presence. On the other hand, expectations are sky-high, any misstep gets amplified by passionate fans, and licensing costs can eat into profits. All in! Games is betting big that they can deliver something that honors the IP while standing on its own as a quality open world experience.
Looking at recent history, licensed open world games have a mixed track record. Hogwarts Legacy was a massive success. Gotham Knights struggled despite the Batman IP. Avatar Frontiers of Pandora had strong reviews but underperformed commercially. The quality of the game itself ultimately matters more than the IP attached to it, though a strong IP certainly helps with initial sales and awareness.

Final Thoughts
Project Rainbow represents a fascinating mystery in the gaming industry right now. A mid-tier publisher spending four years on an open world game based on a globally recognized IP is not something that happens quietly without generating massive interest once the details leak. The question of which IP All in! Games secured will dominate speculation until they finally reveal it officially.
What’s encouraging is the development timeline. Four years suggests a team that’s taking the time to do things right rather than rushing to market with a half-baked licensed game. The gaming landscape is littered with failed IP adaptations that prioritized hitting a release window over actual quality. If All in! Games can deliver an open world experience that does justice to whatever franchise they’re working with, they could have a legitimate hit on their hands. Until then, the guessing game continues, and every gaming community with a beloved IP will wonder if Project Rainbow is finally bringing their world to life in open world form.
