3 new maps, available on April 15th.

1 is a remake of Halo 1's snow level, Sidewinder. This will contain all vehicles, including a scaled back version of the Hornet.

1 is a remake of Halo 2's mini snow base, Lockout. This time, it'll be remixed so it'll feel like you're playing in a nighttime atmosphere.

The last one looks like an abandoned town.
