Microsoft has unveiled a browser-based demo of Quake II, highlighting the capabilities of its Copilot AI platform. Users can navigate a single level, experiencing a unique interaction with the AI model. However, Microsoft admits that the demo has limitations, such as fuzzy enemies and inaccurate damage counters. Critics, including game designer Austin Walker, argue that this approach misunderstands game mechanics and preservation. Despite the shortcomings, the demo provides an intriguing glimpse into AI's potential in gaming. Microsoft views this as a research exploration rather than a fully-realized game experience.
