I had this idea for a decent halo 4 map today i dub the Mine (name not the best i know). It would take place in a crystal cavern that is used to mine the crystals used in the needler weaponry, so basically, its a big pink cave. The map would feature close quarter fighting, destructable stalagtites (or whichever hangs from the ceiling ), and explosive pink crystals. There would also be some evidence that the elites (or brutes) have been mining, including stairways, minecarts (for movable cover), and grav lift elevators.
Anyway thats my idea. Hope you all enjoyed it, and please, help me come up with a better name
