Tips and Tactics[]

  • This gun is good for spraying as the bullets won't spread out of the crosshair.
  • Those who don't have Blaster can use this as a replacement.
  • The B mode of it is very inaccurate when scoped in long range, as it takes many shots to kill a single enemy because of its accuracy. However, it has accurate shots while moving and recommended to hunt zombie using B mode.
  • A mode can be used to run from zombies, and Deadly Shot works well with this gun. Recommended to find a huge target to activate deadly shot like Heavy Zombie, Stamper, Ganymede, Deimos, etc.
  • When chased by zombies, take caution that when pressing the 1 Key (Primary Weapon), it won't immediately change. To prevent this thing occur, please always quick switch it to the A mode so you don't need to press 1.
  • Do not quick switch it while changing mode, because it won't work like M4A1.
