Heroes of Might and Magic II: The Succession Wars

Half-Life: Extended is a large mod for Half-Life that expands the original campaign by combining content from Blue Shift and Opposing Force, adding new levels, reworking NPCs and maps, and increasing world detail. The campaign has become larger and more varied, making Half-Life: Extended feel like an almost entirely new game.

Half-Life: Enriched is a mod that carefully updates and expands the original Half-Life campaign maps. The author improved lighting, doubled texture resolution, and reduced loading screens between levels while keeping the authentic gameplay intact.

Resident Evil: Cold Blood is a Half-Life mod based on the Resident Evil Outbreak universe that immerses you in the atmosphere of survival during a zombie apocalypse. You'll need to wisely use limited ammunition, mix powders, manage inventory, and think through every move.

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.

Solitary Echoes is a total conversion of Half-Life set in the Aliens universe. You play as an engineer at LV-513 base, which is under attack by xenomorphs. Having hidden in a maintenance room, the protagonist decides to venture outside after weeks to fight for his life, find help, and discover the truth about what happened.
