Microsoft is establishing 'Xbox Labs', a new division dedicated to reverse engineering experiments involving decompiling and recompiling video games. This signals that Xbox is officially embracing the trend where modders use AI to break down game code, port titles to new hardware, and remix them with other games.
Xbox CEO Asha Sharma introduced Xbox Labs in a memo to employees published on the official news site on the 13th, local time. It is a small group composed of game makers, engineers, and scientists, with Xbox CTO Scott Van Vliet tasked with setting up the team. Sharma stated that they will "build in the open, learn from what people do, and measure success by whether more people are playing and creating."
The catalyst stems from a flood of recent cases over the past few weeks where games were decompiled and rebuilt to run on hardware they were never originally designed to support. Windows PC builds have been translated for Apple Silicon or ported to run inside web browsers via WebAssembly and WebGPU. Sharma noted that these experiments challenge long-held industry assumptions, such as the tether between software and hardware and the boundary between creation and play.
In fact, a browser port of 'Halo: Combat Evolved' emerged, while 'Call of Duty: Black Ops' and 'Minecraft' were also decompiled to run on the web. Mods that mix one game's source code into another have also gained traction, with videos showing Minecraft's Steve battling an 'Elden Ring' boss going viral.
This is not Xbox's first foray into this territory. Since the Xbox One era, Microsoft has operated a backward compatibility program using emulation to run Xbox 360 and original Xbox games, and in July, it launched an early release compatibility program running four original Xbox games on Windows 11 PCs. However, while backward compatibility relies on emulation to mimic hardware environments, the approach in question differs in that it breaks down code and rebuilds it.
In particular, Sharma assessed that this trend produces "unmistakably good outcomes for players," even when it "challenges existing business models." She explained that coding became the first major workload for AI agents because software can be written, run, and tested, arguing that games share many of those same properties. She also cited Xbox figures claiming that users spend over 72 billion hours annually playing Xbox games—roughly five times the estimated time spent writing code worldwide—though this remains an assertion made by Xbox.
However, specific projects, reveal timelines, and the scale of the initiative have not yet been announced.
While Sharma stated that tools built by Xbox Labs would be shared with developers across the industry, she drew a clear line, reiterating that core priorities—responsible management of game development, hardware, IP, and community—remain unchanged.
The key variable is IP. It remains unclear how Microsoft will handle decompiled products created by modders using publishers' IP and distributing them for free. Publishers have taken aggressive action against decompilation-based projects in the past, as seen when Nintendo issued copyright takedown notices for 'Super Mario 64' PC port files.
Sharma, who succeeded Phil Spencer as Xbox head in February this year, has stated since taking office that there is "no tolerance for bad AI." Amid divided opinions within the gaming industry regarding AI coding, how far Microsoft is willing to embrace decompilation-based modding is expected to be the new team's first major test.
