AirMech puts the player in similar perspective of a giant transforming robot that can fly above the battle as well as land on the ground to aid units. The game revolves around the player controlling their AirMech directly and then building units to assist in achieving whatever the goal of the game mode is. The player can build units and pick them up and can place them down on the battlefield to take part in the battle. The main objective of the game is to destroy the other team's fortress and/or keep the player's fortress running. The fortress spawns creeps which are infantry units that can capture outposts. Outposts are buildings that can heal AirMechs and units if they are picked up.
