The macro for non-stop firing from a grenade launcher in Call of Duty: Modern Warfare II allows you to significantly increase the effectiveness of your game. To work with any assault rifle, you can use under-barrel grenade launchers, as well as under-barrel shotguns and ZVS. To use the macro, go to the map from the list: Almazra, Ashika or Vondel. It is recommended to assign macro activation to the 4th mouse button to ensure ease of use during the game. There should be stun, smoke and light grenades in your tactical equipment cell. And in the combat equipment cell, there must be a throwing knife, semtex, termite and ZVB. Otherwise, the macro may not work correctly, which will reduce its effectiveness.
