HL2-RS: a partial Rust reconstruction of Half-Life 2

HL2-RS partially reconstructs Half-Life 2 in Rust and Bevy, reading maps, models, textures, animations, and sounds from an installed copy. Its source separates Source asset readers, simulation, UI, and rendering; the author reports working menus and selected city sequences while the campaign remains incomplete.
