In essence, Micro Missiles are even smaller versions of missiles designed to launch en masse to inflict serious damage to an AC. They are designed specifically to overwhelm AMS (Anti Missile Systems). They are highly effective weapons with moderate ammunition loads with respectable power as well as load weight and energy drain. In Armored Core 4, this weapon is renamed the scatter missile and fires far more, abeit less powerful versions, of these missiles, and are no longer as effective against Anti Missile Systems. Its heavy weight and high energy drain also makes it very difficult to double wield such weapons and it's ammo cost makes it extremely expensive and can run ammo costs up 100,000 credits or higher.
