A Flakvierling 38 on the roof of the Castle.

The Flakvierling 38 is a fixed weapon the player can access in Wolfenstein.


The Flakvierling 38 (Flugabwehrkanonevierling 38, lit. "Anti-aircraft cannon quad 38") was a quadruple mounting of the German Army's FlaK 38 light anti-aircraft gun, firing the same 20x138mm B round as the single real weapon and produced from 1940.

In-game, the Flakvierling is functionally a more powerful MG42, with the same mechanics; it has infinite ammunition and is governed by a heat gauge, which uses the same icon as the MG42 heat gauge. The gun traverses slightly more slowly than the MG42, meaning the player must plan ahead somewhat more in order to engage enemies successfully.


The first encounter with the Flakvierling 38 is in the mission Castle; a group of four are present on the roof of the Castle and are used to fight the Queen Geist and her minions. These guns are unique in that BJ cannot leave them after entering; they will be destroyed automatically once the player destroys each of the Queen's egg sacs on her abdomen, whereupon the player must quickly run to the next emplacement.

Flakvierlings are later encountered on a rising platform in the mission Radio Station, overlooking a large yard in the mission Airfield and on the Zeppelin's gondola; in these cases, BJ can enter and leave these guns normally, though the one in Radio Station takes longer to dismount than the others. The Zeppelin also has a gun deck with a number of Flakvierlings pointed out of narrow firing ports; these have very limited traverse, but can be used to shoot down the Rocket Troopers who spawn to protect the Zeppelin's engines if the player runs back to them.


  • A Flakvierling actually had a normal crew of eight and the guns were fed with 20-round box magazines; it would require at least two extra people to keep it loaded. Having large crew-served weapons operated by one person is fairly common in videogames.
  • The barrels seem to fire at random; the real weapon has two foot pedals for firing which operated diagonally-opposite barrels.
  • The Flakvierling 38 will never overheat in real life as it did in the game, the gun will need to reload before the overheat occurs.
