Deep Impact is an impressive but unfinished total conversion for Generals Zero Hour that moves the game's events to a futuristic 2055 after Earth's collision with an asteroid. The mod adds two factions and includes several simple maps.

Halo: GoldSource is a mod for Half-Life that recreates the atmosphere and gameplay style of Halo, including Slayer and Firefight modes, iconic weapons and maps from the original shooter, but runs on the GoldSrc engine.

C&C Tiberian Odyssey is a total conversion for Tiberian Sun that completely overhauls the storyline, units, graphics, and audio, moving the events to 2041 - 11 years after the events of C&C: Tiberian Sun - Firestorm, featuring new factions and maps.

Heroes IV - Ultimate is a large-scale mod for Heroes of Might and Magic IV that expands the original game without changing factions. It adds new creatures, spells, artifacts and abilities, HD mode, improved graphics and icons, new objects and reworked campaigns, making the game more modern and content-rich.
