It is good to abuse this item's damage computation. The damage output of this item is based on the damage dealt to an enemy, NOT the base damage of the character dealing the damage. So if ever an attack landed a crit, the missile damage spawned when it procs will have 300% amplification of the damage just dealt to the enemy. It is unconfirmed whether which damage of the piercing attacks like FMJ would be the basis of the missile, but it is assumed that the nearest enemy's taken damage is the basis.[verification needed]

Sadly enough, this does not apply to AtG Missile Mk. 2, it bases its damage on the base damage of the character.

Character SynergiesEdit

  • When in a large group or mob of enemies, Acrid's Epidemic spreading can fire a very large burst of these missiles.
  • High rate of fire characters such as commando can make use of it in the same way, but without relying on clustering enemies.

Item SynergiesEdit

  • This item synergizes well with other items that increase the players attack speed (such as the Soldier's Syringe) since more hits means more procs.


  • The full name of the AtG Missiles is actually the AtG Viper Missiles.
