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, rather than the base damage of the character dealing the damage. This means that if an attack lands 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 Commando's Full Metal Jacket would be the basis of the missile, but it is assumed that the nearest enemy's taken damage is the basis.[verification needed]

This does not apply to AtG Missile Mk. 2, which bases its damage on the base damage of the character.

Character Synergies[]

  • When in large groups of enemies, the spread of Acrid's Epidemic 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 Synergies[]

  • This item synergizes well with items that increase the players attack speed, for example, the Soldier's Syringe, as more hits will result in more procs.


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