A Haywire Missile is a special type of support missile used by Imperial Titans. Like other support missiles the Haywire Missile takes up one carapace point on the Titan and is usually fitted before a battle.
When a Haywire Missile explodes it creates a burst of electrostatic and radioactive pulse waves which disrupt the target's electrical systems. This weapon is particularly deadly against other Titans since it directly causes damage to the Titan's Mind Impulse Unit. However a Titan with active Void Shields is completely immune to the haywire effect and will suffer no damage.
