WinDoom (Microsoft)

WinDoom was a preliminary port of Doom v1.8 to Microsoft Windows 3.11 by Gabe Newell using the newly developed Win32s and WinG technologies. This port never made it past beta testing due to the impending release of Windows 95. Two beta versions were unofficially released and are available in the /idgames historic archive.

This code base was later upgraded to the full Win32 platform in order to exploit the DirectX technology available on Windows 95, where it became known as Doom95.
