Gameplay videos have been released for each of the three new maps that are included in the "Noble Map Pack" for Halo: Reach
The first map is Anchor 9 and is the smallest of the three. Bungie
describes Anchor 9 as allowing "2-8 players to face off in game variants including Free for All, Team Slayer and Team Objective".
Tempest is next on the list. Bungie states that the map "supports 8 – 16 players and offers a variety of modes including Free for All, Team Slayer, Team Objective and Big Team Battle. Tempest also provides players with a huge Forge palette, allowing them to create new custom map variants that can be shared with the community-at-large"
Finally, "Breakpoint" is the largest map of the three. It "offers multiplayer mayhem for 8-16 players, and supports the Invasion and Big Team Battle game variants."
You had better start memorizing the maps and weapon spawns if you want to be top of the leaderboards when the map pack is released.
"Noble Map Pack" will be released on November 30th, at a cost of 800 MSP.
