Tiberian Sun Client is a standalone version of Tiberian Sun that fixes all known game bugs and adds new features: convenient file structure for modding, extended game options, preset starting positions and teams. The client preserves the original gameplay while improving stability and game convenience.

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.

Scorched Earth is a large-scale overhaul of Red Alert 2 that preserves the canon while making factions more unique, adding new units, and improving balance. The AI has become extremely tough, and weapons more deadly. New maps, objects, and terrain elements have also been added.

A fan-made port of the early alpha version of Half-Life to the classic GoldSrc engine, featuring updated maps and content.
