Half-Life: MMod is a fan-made modification for the original Half-Life. Much like the "MMod" modification for Half-Life 2, HL1: MMod aims to enhance the game's visual presenation, update the gameplay and gunplay systems, and add some much-needed quality-of-life improvements. And as of a recent game update in March 2023, HL1: MMod features basic support for creating MMod-compatible versions of custom campaigns and community-made mappacks/mods.

The following guide details several campaigns that are compatible with Half-Life: MMod. I aim to update the guide on a semi-frequent basis as I continue to test various mods for compatibility with MMod.

Thank you for reading, and have a very safe and productive day.
