  • For classic matches, a shot to the head from SKULL-6 can instantly kill an enemy.
  • 100 rounds of SKULL-6 can deal around 3400 ~ 6800 damage to zombies.
  • Spraying makes the weapon really inaccurate. Always zoom in for middle to long range combat unless you are inside enclosed areas such as the vents and the zombies are close to you.
  • The zoom rate is similar to SKULL-5. The first right click activates the scope but not the zoom.
  • This weapon can effectively penetrate barriers in Zombie Scenario maps.
  • Using the scope increases accuracy and lowers recoil but it also lowers the weapons rate of fire.
  • This weapon has an advantage over the other machine guns when fighting bosses that needs precision such as the zombie boss. Angra, since you can zoom via the weapon's scope while it is flying and AMP Suit, use the scope to attack from a distance.
  • Using the Deadly Shot ability, this weapon performs better than the other Skull machine guns since it has the highest firepower out of them all.
  • A 100 rounds of SKULL-6 can deal around 23,000 ~ 25,000 damage to bosses, provided that the firepower has been maxed.
