A custom version of the video game Doom can be played inside Microsoft Word. The demonstration was posted on January 20, 2025. Wojciech Graj made the modification available on GitHub. To run the game, users must enable Visual Basic for Applications (VBA) in Word, accept security warnings, and use a recent version of Word on Windows with an x64 processor. Word has supported VBA for decades, allowing users to write macros, but the language also permits code execution that bypasses some security features. The process does not require additional software beyond the game file and the VBA‑enabled Word document. Users have reported that the game runs at a playable speed, though performance depends on the document's complexity. Microsoft has not commented on the feasibility of officially supporting game playback in Word, and the approach raises security concerns because VBA can execute arbitrary code. Security experts advise disabling VBA when not needed and caution that running third‑party scripts may expose users to malware. The hack demonstrates the flexibility of Office scripting but does not indicate a broader shift in how Word is used.
