The original Half-Life Goldeneye Modification Team stopped developing because of lack of time in their personal lives. They stopped around 1.9c.
I am a few others have picked up this MOD and continued it, but we need a C++ programmer to do so.
If you are interested in creating a modification for Half-Life based on Nintendo 64's Goldeneye, please let us know.
Thank-You,
The Goldeneye MOD Team
