Three new maps and an update for the Forge are on the way for Halo 3 in April, Microsoft announced today.

The Legendary Map Pack will feature three new multiplayer environments: Ghost Town, Avalanche and a third, unannounced location. The pack will be 800 Microsoft Points (US $10) and is scheduled to hit the Xbox Live Marketplace on April 15.

Here�s how Microsoft and Bungie describe two of the new maps:

Ghost Town is a battle-scarred maze of narrow passages and dangerous ruins outside the once-prosperous city of Voi. Collapsed ceilings and shell-battered buildings provide both valuable cover and deadly traps, as catwalks and stairways take the fight from claustrophobic ground combat to dizzying rooftop battles. Ghost Town is a mid-sized map ideal for Team Slayer games and smaller, objective types.

Avalanche is a tribute to Sidewinder, a "Halo: Combat Evolved" fan-favorite. This massive, vehicle-oriented objective map adds a twist to its classic predecessor with all new interiors, dramatically reshaped exteriors and brand new vehicle variants. Take a ride and admire the visual variety from the cockpit of the retuned Hornet.

The third map is still a mystery, but a Microsoft news release said it will be "another returning classic… fans of smaller Slayer maps, it�s time to get excited."

In addition to the new maps, Halo 3 players will also see some additions to the Forge when they download the expansion, but Microsoft hasn�t provided any details just yet.
