Original Characters (young)
The Mauser C96 performs nearly identically to the M1911. It has very weak damage (taking multiple magazines to kill a single zombie even on the first rounds, though it seems to be slightly stronger than the M1911 as it kills in two magazines rather than three at round 3), medium firecap, a magazine of eight rounds and slight recoil.
- When Pack-a-Punched, it will fire the same beams as the Pack-a-Punched Ray Gun Mark II.
- This is the third firearm to replace the M1911 as a starting weapon for the Zombies mode in the series, the first being the M60 in Dead Ops Arcade and the second being the Makarov PM in Call of Duty: Black Ops (Nintendo DS).
- Boomhilda is a reference to the Germanic mythological story of Brynhildr. However, it may also be a reference to the Mauser C96's nickname "broomhandle".
- The ACOG Scope is the same model of the ACOG Scope for the NATO weapons on the campaign and the Python's special ACOG scope from Call of Duty: Black Ops.
- It is possible to carry a Boomhilda, and a Mauser that has been dug up. However when the second Mauser is Pack-a-Punched, the Boomhilda carried by the player will only receive more ammo, and the player loses their secondary weapon. This can also be done with most box weapons in a variety of ways on all maps.
- The player is unable to stalk (walk at regular speed while aiming down sights) while looking down the ACOG Scope on the Boomhilda.
- Boomhilda retains its one-hit-headshot kill until round 35, and stays a two hit headshot for awhile.
- The ACOG Scope has a regular design with no recticle on the Boomhilda.
- The Boomhilda is extremely effective against the Panzer Soldat. It is possible to kill him in just two hits in the head at any wave but extreme accuracy is needed.
- The Boomhilda, both in appearance and in the shots fired, closely resembles Han Solo's blaster pistol from the popular Star Wars franchise.
