  • Original: Not recommended as it could waste the user's money.
  • Deathmatch/Team Deathmatch/Basic: Recommended due its fair damage, accuracy, low recoil, high rate of fire, light weight and usable scope in single mode.
  • Use dual mode in close combat as it has high damage and very high rate of fire.

  • Use A mode to efficiently escape from zombies or as backup when using a melee weapon; use B mode to kill zombies.
  • Take note that B mode is not suitable to engage zombies in open areas due to it's heavy weight. Instead, use melee weapons such as the Skull-9 or Nata Knife to kill zombies while using A mode to stun or escape from zombies.

  • It can kill the Titan easily due to its high damage and very high rate of fire.
  • It can also be used to destroy barriers very quickly.
  • SKULL-3 is also good in dealing with bosses.

  • Tactics facing SKULL-3 users[]

    Original[]

    • SKULL-3 users are fast, mobile, silent and deadly if the users are experienced.
    • With B mode, they can annihilate your whole team easily with 70 rounds.
    • Sniper rifles and far-middle ranged weapon are recommended, don't try to approach them directly unless you have good skills.

    Zombie mods[]

    • Usually, SKULL-3 users will go with B mode, so they're deadly but slow in movement. If they're not in ducts, infect them quickly, especially when they are reloading in B mode.
    • With Deadly Shot, SKULL-3 in B mode can take down several <6000 HP zombies in ducts.
    • Light type zombies are recommended when dealing with SKULL-3 users.
    • SKULL-3 has high stun (nearly the same with MP5) and low knockback power.
    • Try not to engage SKULL-3 users alone, especially if they use the Deadly Shot skill.

    • An exploit exists whereby the user will automatically reload the weapon upon switching between A and B modes.
    • Despite the scope being obstructed by its cap, it can still be used in A mode.
      • The scope has the words Aopoint on the side, a parody of the real-world company Aimpoint.
    • Oddly, in B mode it's heavier compared to SKULL-4, despite it being a submachine gun.
