- For original version, see M134 Minigun.
The modified version of M134 Minigun fed with 300 rounds of 7.62 NATO. It has a strong secondary fire mode that is very deadly but limited with overheat factor. It can also be lifted for fast running.
- Deals very high damage to zombies
- Has rapid fire mode
- High accuracy
- Very high rate of fire in both modes
- High stun and knockback powers
- Very low recoil
- Light weight for a machine gun
- High magazine size
- Using B mode will cause it to overheat
- Usable only when the player is chosen to become Hero/Heroine
- Long reload time
- In B mode, it can shoot 3 bullets per shot.
- B mode provides higher rate of fire than A mode. However, it causes overheat, which takes time to cool down the barrels before the next usage. This does not apply when players switch weapons.
- If a player shoots out a full magazine (300 bullets) in B mode, it takes 21 seconds to cool down. The cool down time is directly proportional to the amount of time fired in B mode.

- Strangely, Dominique appears in a poster in which he wields or possess this weapon, even though the weapon can only be used by Heroes, followed by the fact that they cannot drop their primary weapon in any case.
