Half-Life: Residual Life is a single-player campaign for Half-Life from a South Korean team, which is a continuation of the Residual Point mod, where G-Man somehow reboots the space-time continuum, leading to an alternative timeline of events at Black Mesa, where you play as a scientist trying to escape to the surface.

Half‑Life: Decay: Solo Mission is a Half‑Life mod that ports all chapters of the PS2‑exclusive expansion Half‑Life: Decay into a fully playable single‑player campaign while preserving the original gameplay.

Life's End is a large-scale fan campaign for Half-Life that immediately stands out with its unusual approach to storytelling. Unlike most other projects, the focus here is not only on shootouts and familiar elements from the original, but also on absurdity, irony, and unexpected plot twists.

Catharsis is a short but atmospheric mod for Half-Life that tells the story of an unnamed scientist trying to escape from Black Mesa during the disaster.
