"So this is what Maxis was keeping secret!"
Edward Richtofen

The Thundergun is a wonder weapon featured in the Zombies game mode and can also be found via an Easter egg in the Call of Duty: Black Ops campaign mission "Numbers". It appears in the Zombies maps Kino der Toten, Ascension, and the Call of Duty: Black Ops edition of Nacht der Untoten and reappears in Call of Duty: Black Ops III on the zombies map Revelations and the remastered versions of Nacht der Untoten, Kino der Toten and Ascension.


The Thundergun was originally thought by Richtofen to have been created by Dr. Maxis and that Maxis had been deliberately hiding it from him as he grew to not trust Richtofen, although this could mean that Richtofen did not trust Maxis and became paranoid. Richtofen even referred to it as the DG-3 (meaning he considered it to be the Wunderwaffe DG-2's successor). However, one of the radios in the map, Ascension reveals the true creation of the Thundergun. It was a Russian weapon codenamed "Project Thunder" and was being worked on by the Ascension Group under Gersh's direction. Gersh knew about its range problem and was trying to fix it. He also knew about its small ammo (power cell) count.


The Thundergun is a large, cannon-shaped weapon that fires blasts of incredibly strong compressed air. It has no iron sights, meaning it must be fired from the hip (although when observed in third person, it is held on the shoulder). It is able to kill large numbers of zombies with a single shot, sending them flying backwards or up. Those who are not killed by the blast are thrown backwards and will remain on the ground for a few seconds before getting back up. The Thundergun holds two rounds in its magazine, and has 12 rounds in reserve. The Thundergun can only be reloaded when all shots have been fired. The Thundergun is important during the later rounds as it is useful for clearing large groups of zombies in order to reach a downed teammate or make an escape. It is extremely useful when swarmed as it will easily kill a large group of zombies in one shot.

Trivia Edit

  • Call of Duty: Black Ops
  • Gersh can be seen holding the Thundergun on the Ascension poster.
  • In Zombies mode, while a single kill with the Thundergun gives the player 50 points, each additional kill provides less points and the total amount can not exceed a total of 300, meaning that killing 24 zombies will still add 300 points to the players score.
  • The sound heard when receiving the Thundergun in "Numbers" come from transmissions of GKNOVA6.
  • The gun has "Остережение" written on its side, which is the misspelled Russian word for "Warning", which correctly spelled is "Предостережение" (Predosterezhenie).
  • The two red glowing lights on the front of the canister when loaded into the gun indicate how many shots are left in the magazine. When upgraded there are three lights visible as one of them is hidden by other parts of the gun. This is fixed on the iOS/Android version of the game. This is also the case in Black Ops III.
    • From the animation, it appears as if it should be able to hold a maximum of eight rounds should Maxis and Gersh have fixed the Thundergun's magazine problem.
  • If zombies that are knocked down by the Thundergun's blast are attacked by players, they will instantly be back up on their feet, instead of slowly rising up.
  • The Thundergun deals no friendly fire damage in "Numbers".
  • There is an unusable Thundergun in a metal locker in "Five". It is in the same room as the unusable Winter's Howl and Death Machine.
  • If the player turns off rag doll effects, zombies will not fly backwards when shot; they just fall as if they were taken out by conventional weapons.
  • Occasionally, zombies caught at close range in the blast will not be affected at all, as if the weapon missed them entirely.
  • "Stainless Steel" can be seen written on the Thundergun.
  • The Thundergun was originally going to be a usable weapon on "Five", as there are quotes in the games files for each character, as can be seen here.
  • The Thundergun in "Numbers" can be reloaded mid-magazine.
    • When the Thundergun in "Numbers" is reloaded mid-magazine, the current magazine will disappear and the empty reload is executed, as the Thundergun has no mid-magazine reload animation.
      • Also, the glowing lights will still be visible, even though the magazine is out.
    • In the Nintendo Wii Version of Call of Duty: Black Ops, if the player obtains the Thundergun from the Mystery Box on single player before updating their game, it is possible to aim down its sights.
      • It is also possible to reload mid-magazine on single player before updating the game.
      • In the Nintendo Wii Version of Call Of Duty: Black Ops, if the player obtains the Thundergun from the Mystery Box, they will notice that there is no orange/red glow on the Thundergun.
    • Before an unspecified patch, the Thundergun could be reloaded mid-magazine on Kino der Toten.
  • Zombies killed by the Thundergun will not drop power-ups.
    • However, in the mobile version of the game and Black Ops III, they are able to drop power-ups.
  • The ZeusCannon's wind shot looks slightly purple on the inside.
  • An ad for the Thundergun can be seen on the loading screen for Moon.
  • The Thundergun has visible iron sights, although the ability to use them was never featured in the game.
  • In the mobile version, Zombies are instead turned to ashes instead of being blasted away.
  • Call of Duty: Black Ops II
  • According to Call of Duty: Black Ops II PC game files, the Thundergun was originally going to appear in the game, but was removed for unknown reasons.
  • Call of Duty: Black Ops III
  • The Thundergun does not have a wall running animation.
  • Though the Thundergun lacks the ability to zoom aim, from a third person view, the character model retains the zoomed in animation.
