Update By: Dragonsbrethren
After a few weeks of work (And a few months of slacking off) my Silo mission has finally been released. The mission uses the same map as the original but plays entirely different, you must rescue hostages, prevent missiles from being launched, and unmask and eliminate the new leader of Janus. Check the readme or in-game briefing for a more detailed description of the storyline behind the mission.
Get it
here or follow the relevant link to its page on Goldeneye Vault. A movie of SubDrag playing an earlier test version is available
here. A few things have been changed since that movie was made but it should still give a good idea of how the mission plays.
