Halo 3 Mythic (OpenH3M)
GTTeancum/OpenH3M
OpenH3M: a native Windows static recompilation of the Halo 3 multiplayer disc bundled with Halo 3: ODST (Halo 3 Mythic), built with the ReXGlue SDK. In beta 0.8 the full menus with their 3D backgrounds, Custom Games, one-to-four-player local split screen, and Forge all work; Theater can be entered, but recording and saved-film playback aren’t fully validated, and System Link is untested. Matchmaking and Xbox Live aren’t supported and never will be. The game keeps its original 30 fps cap, shows the frame rate in the window title, and opens in a 1280×720 Direct3D 12 window. It supports Xbox controllers and, for player 1, the keyboard. Beta 0.8 came out on August 17.
You needThe files extracted from your own Halo 3: ODST Multiplayer Disc (Disc 2), in a game folder next to the executable, with default.xex and the maps folder. Plus 64-bit Windows 10 or 11, a Direct3D 12 graphics card, and Xbox-compatible controllers, strongly recommended, especially for split screen.
