Tactics facing SKULL-5 users[]

Classic Battle
  • Avoid medium and long range contact.
  • One-hit-kill sniper rifles like AWP are recommended when facing SKULL-5 users.
  • SKULL-5 has no crosshair, so use this as an advantage by assaulting the user in close range.
Zombie Mods
  • Your mobility will decrease temporarily when shot by SKULL-5 due to high stun power, so be careful.
  • SKULL-5's bullets will knock Light Type zombies far away. It can also knock incoming normal and heavy type zombies in midair away.
  • Cooperate with other zombies to take down SKULL-5 users for a higher chance to infect them. Do not go alone unless you have proper skills.
  • Use zombies with small hitboxes like Light zombie to avoid SKULL-5 bullets. This choice needs a proper skill to dodge.
  • Run away when SKULL-5 users turn on Deadly Shot, or you'll be killed instantly if your HP is below 4000.
