MP5K A4-Halloween is a special sub-machine gun variant of MP5K A4 featured in CrossFire.


MP5K A4-Halloween features a Halloween-themed paint job to celebrate Halloween 2016.

Despite using a new model with a shorter magazine, this gun actually has a higher 45-round capacity (+5), plus a slight enhanced firepower. Also it features a horror laughing sound effect when reloading, similar to Machete-Halloween's when using RMB attack.

  • Unlike the original MP5K A4, the Halloween variant uses a short magazine model (which holds only 15 rounds in real life), which is very inaccurate because it has a 45 round capacity in-game.
    • However, the Halloween variant's killmark depicts the SMG with a long magazine, instead of its short one.
  • In CF Vietnam, this gun was originally put into second prize slot (the first being Machete-Halloween) in the 2016 Halloween capsule, but by the time the patch was released, it was put into first prize slot, pushing Machete-H into second prize slot like most other servers.
  • In CF Philippines, this gun was added on Halloween 2016 even though the stock variant is not yet released.
