Halo 3's newest map pack - called 'Legendary' is coming on April 15th replete with three new maps: Ghost Town, Avalanche and an as yet unnamed one. Prepare for the rumour and speculation on what it will be called to start, well, as soon as you stop reading this story really. What we do know is that fans of smaller Slayer maps, should prepare to "get excited".

The latest Halo 3 DownLoadable Content will set you back, 800 Microsoft Points - but as it comes from Bungie and it adds to Halo 3, you're not going to sniff at that.

Here's what we're told about the maps - well, all except for the unnamed one:

"Ghost Town is a mid-sized map ideal for Team Slayer games and smaller, objective types. 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.

"Avalanche, is a tribute to Sidewinder, a Halo: Combat Evolved fan-favourite. 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."
