Myomer Accelerator Signal Circuitry or MASC, allows a Mech to move much faster at the expense of generating excess heat. MASC is engaged by simply holding the "Left Shift" key while moving. The significant speed boost that results can allow for quicker attack runs, but limits maneuverability slightly, much like modern-day afterburners or nitros. While using MASC keep a watchful eye on the Temperature Gauge as the heat will rise while engaged. Care must also be taken when using MASC, especially in conjunction with Jump Jets or Energy Weapons, as this can result in dangerous amounts of heat. Variants equipped with MASC are great for Capping Bases.
Introduced in 2740 by the Terran Hegemony, the Myomer Accelerator Signal Circuitry (MASC) is a piece of equipment that allows a BattleMech to move at twice its walking speed. However, actuators were not built for this kind of stress, and prolonged usage of MASC systems can damage the leg actuators of a BattleMech. Although this is unlikely to immobilize the BattleMech, the danger of destroyed actuators is enough for cautious warriors to limit their use in battle. MASC was one of the many pieces of Star League technology that became LosTech in the Inner Sphere during the First Succession War, becoming extinct in 2795.
The following Variants equip with MASC:
