The Waffe 28 (referred to as MP28 in the game files) is a fully-automatic submachine gun featured in Call of Duty: Infinite Warfare and Call of Duty: WWII.

Call of Duty: Infinite Warfare[]

"Full-auto ballistic firearm. Modest fire rate and magazine grip provide natural stability."
— In-game description

The weapon appears in Call of Duty: Infinite Warfare as the Trencher. It was added to the game on the May 2nd, 2017 update and is only available from Supply drops, although bots sometimes wield it and will drop it upon death.


Like all of the other DLC weapons in the game, the Trencher can be unlocked through various different methods, such as completing the main challenge, obtaining a weapon variant of it from Supply Drops or having the Season Pass. The main challenge to unlock the Trencher is to complete a total of 20 matches where the player obtained ten kills using either the OSA, MacTav-45, TF-141, S-Ravage, M1 or Hornet.

The Trencher possesses a moderate fire rate and has low recoil due to its magazine grip. Equipping the Blitzkreig variant also gives the weapon a Celerity-like effect of increased fire rate when hipfiring, despite not being shown on the variant stats.


Letter from the QRT-M5TR[]

On August 14th, 2017, a newsletter was released from the QR-M5TR, detailing the character's process of moving the Trencher from the QR-M5TR collection and into the Prototype Lab.[1]

The letter reads as follows;

"Dear Trencher,

If you’re reading this, you’re already gone. I know you’re going to be great out there but that doesn’t make this any easier. You’ll go out into the world and do great things: provide accurate, suppressive fire, demonstrate diminished spray while the user is sliding and enrage noobs. As for me? I’ll stay here in my shop and try to not get too attached to other guns in my collection. I never can. You’re all just too special.

What I’ll remember about you the most is your spirit. Even from your earliest prototypes, you were a fighter. You never had the farthest sight, but that never mattered. You worked hard and, ultimately, your focus, your determination and your accuracy are the things that define you.

My favorite Instagram account once posted the following quote in front of a guy in a suit exiting a nice car “Greatness doesn’t see obstacles, only opportunities.” And, Trencher, that’s you to a T. In early testing, when you couldn’t hit water from the ocean, you simply turned your magazine box sideways. Now, that side-inserted magazine box defines you. Or when the assault rifles made fun of you for only dealing modest damage? You were inconsolable. You said, “I can’t help it! It’s how you made me! If only I could throw a grenade at those jerks!” And, look at you now, the only SMG with an available, under-mounted grenade launcher. One of a kind. That’s you, Trencher.

People say merely inputting specifications into a 3D printer and tapping ‘Print’ doesn’t make you an “actual parent” but those people? They’re wrong. I made you. And being a parent means knowing when to let go. So, Trencher, it’s time for me to say goodbye. You weren’t meant to sit around and collect dust. You belong out in the world. It makes me sad. But, I know you’re gonna do great. If I could cry, I’d be sobbing like a human baby. But, it’s good that I can’t because moisture ruins my internal processors.


The Quartermaster"

The Trencher was added to Zombies in Spaceland, Rave in the Redwoods and Shaolin Shuffle, where it can be found in the Magic Wheel. In Attack of the Radioactive Thing, it can be bought from the wall for 1000 points and later returns to the Magic Wheel in The Beast From Beyond.

When Pack-a-Punched via the Pack-a-Punch Machine, it becomes the Moody J28. When Pack-a-Punched again once the Alien Fuses have been installed into the Pack-a-Punch Machine, it becomes the Los Vantes.


Call of Duty: WWII[]

"Automatic SMG with high recoil and highest fire rate in class."
— Description

The Waffe 28 appears in Call of Duty: WWII.


The Waffe 28 is used commonly by German soldiers during campaign.


It is a high RPM and low-damage weapon in the same vein as the M1928 and PPSh-41, and boasts similar strengths and weaknesses to both these weapons. However, the Waffe 28's main strength lies in its extreme fire rate, which surpasses both the M1928 and PPSh-41 and gives it the fastest time-to-kill of any automatic weapon in the game at point-blank range. As such, the weapon is tremendously effective in close quarters.

However, the Waffe 28's effectiveness rapidly drops off, as its performance beyond point-blank range is crippled by poor iron sights, high recoil, and low damage. The recoil pulls harshly upwards and to the left, and is the strongest of any automatic weapon in the game, making accurate gunfire past point-blank a near impossibility unless the player fires in bursts. Even if the player chooses to fire in bursts, the Waffe 28 is a six-shot-kill at range, causing the time-to-kill to plummet and allowing an enemy wielding nearly any other weapon to take the advantage. Steady Aim, Grip and an optic of your choice can help iron out some of the Waffe's flaws. Advanced Rifling should be avoided as kill range isn't substantially increased.

In conclusion, the best way to use the Waffe is to adapt a similar playstyle to that of a shotgunner. Playing aggressive and sticking almost entirely to close-quarters areas allows the user to gain the advantage of surprise and kill enemies before retaliation is possible. Players are advised to avoid any sightline that extends beyond about ten meters; or, if such engagements cannot be avoided, running the Rifleman training option allows the player to carry a more effective long-range secondary, such as an assault rifle or LMG.

Nazi Zombies[]
