Mech Weapons

Source Tech Revolution pg. 102
Engineers have designed and adapted a wide range of weapons for mechs to use. Each weapon combines two factors—the weapon's level and a weapon template—to determine its statistics and MP cost. Mech weapons use many of the same rules as standard weapons, including damage types, targeting Armor Class, damage, range, critical hits, capacity, usage, and weapon special properties.
