- This was first seen in The Art of Halo 3, though it was cut from the retail version of Halo 3.
- If the name of the weapon is read in L33t speak, it appears to say "Gah-Dush" which may come from the sound the rocket makes when it detonates.
- It appears that this weapon was intended as a guided surface-to-surface or surface-to-air missile launcher.
- The G4H-DuSH seems to be at least partially based on the American "Stinger" surface-to-air missile launcher.
When developing the Halo games, Bungie, 343 Industries and Ensemble Studios have had to cut some content from the final games. As such, many aspects of the games, such as vehicles, gameplay, design, and story elements, were not included in the final versions. Many of these elements have been confirmed by such material as videos and commentary on the Halo 2 and Halo 3 Limited Edition DVDs, interviews with developers, and released concept art.
