Heroes can freely alternate between battling on land, or taking off to fight in the air. Players battle over control points using a customised army, and can pick units up with their airmech to drop them off elsewhere. There are many maps to choose from.
A weak computer army plus four human players try to survive against, and eventually defeat a strong computer army within a 2-hour time limit. There are six hero units to choose from, each effective against different enemy unit types and having its own advantages. Players can also recruit and control their own troops to assist in the fight.
