Challenger is a 2 player map for StarCraft.
Given the twisted nature of Challenger’s landscape, it can be hard to find the enemy, though choke points exist for the ground entrances to both bases. Air support is useful, due to the fact that a player's main base features a wide area for landings, not to mention that some resource fields can only be accessed by air.
