Vidmaster Challenge: Annual is a Halo 3 Xbox live multiplayer achievement where the player has to complete the level halo in a four-player Legendary co-op game with the Iron Skull activated, and all players in Ghosts. The achievement is named “Annual” because it only became possible to unlock it after the one year anniversary of the release date of Halo 3. Follow this guide to unlock it!
It is represented by the Iron Skull logo with a green Marathon symbol behind it. The Iron Skull is framed by four stars. (see pic above). No gamerscore points are awarded for this achievement, however it does count towards the unlockable multiplayer Recon armor.
Steps

2. You must play the mission from the start for the ghosts to appear.
3. When on foot stick together in pairs providing cover for your team-mates to the front and rear. When in the ghosts, drive close together and in single file so you all follow the exact same route.
4. Re-group every now and then to make sure no-one has been left behind.
5. Follow the rest of the directions in the video below to successfully unlock this Vidmaster!
