8-map hub set in the Black Mesa military-industrial facility within the Half-Life universe. The game is story-driven and features multiple objectives. It uses the excellent textures of Half-Life, sprite-based enemies and non-player characters from Half-Life, models (some of them interactive), true 3D environments and other features of GZDooM. Tested with GZDooM

Base:
8 levels from scratch + TitleMap. Map01 is based on the initial areas of Half-Life prior to the Anomalous Materials Laboratory. We constructed the entire level using in-game screen-shots, i.e., we did not use a Half-Life editor at all.
Build time:
3 years, off and on, mostly off
