Half-Life weapons, NPCs and vehicles in your Minecraft world.
Bring Half-Life 2 into a single-player Minecraft sandbox. Minecraft stays your main game, while a quiet Half-Life 2 companion supplies the original live weapon models and animations from your own installed copy.
Controls: R reloads; right-click uses alternate fire, zoom or gravity pull. Vehicles use WASD, Space to brake, Ctrl for turbo and Shift to exit. Content is available on the Half-Life creative inventory pages. Physics runs in Minecraft using values read from Source; it is an approximation rather than Valve's VPhysics engine. Single player only.
Requires Windows 10/11 x64, Minecraft Java Edition ownership, and current Steam Half-Life 2 with its included episodes and English voice files. The supplied profile runs Minecraft 1.21.11 with Fabric 0.19.5. Sign in to your Microsoft account once in Prism; the first preparation converts assets from your own games and may take several minutes. No Valve or Minecraft game assets are distributed. Play opens Minecraft's main menu; closing Minecraft closes this session's companion and bridge.
Version 1.0.6 repairs resource conversion and premature session ending, waits for Minecraft before starting its companion, and guards Minecraft's place as the main window. Personal loose overrides are excluded from conversion and explicit custom-folder mounts are removed from the companion profile. The separately reported native memory crash remains unconfirmed; Workshop enumeration can still occur.
