Christmas Invasion

The Christmas Ultimatum is a Heavy weapon introduced in the 13.1.0 update.


The weapon takes the form of an RPG-style rocket launcher.

This weapon is mostly green and has candy cane colors breech in the back of the weapon and on the top of the body. The body of the weapon is mainly green, with several electronic parts and wires on the side of the body. On the bottom of the weapon it has a handle which is made of wood with a red trigger, and a grey shoulder rest behind the handle.

It rocket takes the form of a Christmas tree with purple and yellow lights. The rocket itself creates clusters of secondary explosions upon impact.


This weapon used to be guaranteed one shot kill when it was first released. It's damage was reduced to a 2 shot kill, however the cluster bombs could still finish off the opponent by chance. It can also be a one-shot with Level 6 or higher damage modules.


  • It comes with frightening area damage that lobs out explosives on impact, hitting a wall can rain explosives onto the ground. Overall, a very unforgiving weapon.
  • In game modes where points determine wins it is recommended not to crutch on this as you gain fewer points than having a weapon that can headshot.
  • This weapon is godly on Point Capture, as the horizontal explosions can cause entire point wipes at times, and the high Efficiency can deal with players easily. This can kill players with the Heavy Champion Armor in one go.
  • This weapon has a Cluster Bomb effect, so when the main rocket explodes, it will split into several bombs that resemble that of the Toy Bomber.
  • This weapon can be used for rocket jumping, but you must jump before firing, or else it can take all of your shields, or health.


  • As frightening as the area damage may seem, most of it is horizontal, staying airborne as much as possible will limit the window of getting one-shot.
  • The fire rate is slow, so try jumping and flanking players who use this.
  • Hide behind a wall and use a wall break weapon like Prototype.
    • Be aware that the damage is decreased if you hit someone through a wall.
  • Use a long range weapon such as the Anti-Hero Rifle, as the C.U. does not have great accuracy
  • Attack them when you see the christmas tree starting to appear at the front of the gun because this means the weapon is preparing for another shot. Remember to use your highest damage weapon for this.
