Should your Mech be low on fuel, a beeping sound will instantly play to remind you to refuel.
Heavier mechs with good protection rating of 4 or higher gain a chance to shrug off smaller damage increments completely due to their natural toughness. Mass can influence a great number of things. Mech mass is determined by the mass of each part arms, head, legs, boosters, body of the vehicle. Mechs have new features in FU distinct from the vanilla game but very close to the XS Mechs Modular Edition mod, which the code is based on.
