Mechs are the primary combat units in Mech Crusaders, the units of which the name of the game is also derived. They are little drones which are remote controlled by their commanders. In order to be able to control multiple mechs simultaneously, commanders require a Cortex Retrofitted User-System Advanced Drone Electronic Remote Implant, also known as a CRUSADER implant. As a commander becomes more experienced in the use of this implant, he can control increasingly more mechs. The Mech Shop is where the player can buy these combat units.
