Guard Duty is an upcoming Source engine total conversion mod of Half-Life: Blue Shift, by Tripmine Studios. Initially, Guard Duty and the similarly community-produced Source engine conversion of Half-Life: Opposing Force, Operation Black Mesa, were being developed by two separate teams. Eventually, these teams came together, forming Tripmine Studios, which would become the sole developer of both mods.


A list of features planned for the final release:

  • Complete re-creation of all eight chapters from the original game.
  • Models that push the limits of the Source engine.
  • Multiplayer, including Deathmatch and Team Deathmatch with all the original levels fleshed out. A "capture the flag" mode may be included, but not in early releases.
  • New voices, sounds, and visuals.
  • Level design tweaks to utilize the advanced physics engine introduced in Half-Life 2.
  • A remixed soundtrack including enhanced music from the original along with new tracks.
  • New scripted scenes.
