Lord Zedd | Halo 2 - (Old) Covie Sanctuary Mod @Zeddikins | Uploaded 8 years ago | Updated 1 hour ago
Back in the day (~2007) I did manage to mod Halo 2. I wasn't great at it but besides the guitar hero controller mod youtube.com/watch?v=i6gpRu-hXRw this is the only other mod of mine that I can find from those times.
So this video is mostly documenting the mod, even if it isn't very special.
