  • The Thanatos form will be activated automatically, rather than using the secondary fire (RMB by default) to transform or charge the blades.
  • The THANATOS-3 stacks up to 12 blades in three sets. However, it can launch any one of the three sets at one's disposal. Blades can be stacked up to three times: 12 bullets = 2 blades; 24 bullets = 6 blades; 36 bullets = 12 blades.
  • Once the blades are launched (RMB by default), the gun will revert back to its original form.
  • Upon hitting a target (except walls), the blades will momentarily stun and surround the target, decreasing their HP for 5 seconds. This also affects multiple enemies should the projectiles link up.
  • When the blade is surrounding the target, it will emit a loud blade cutting sound which disturb nearby players hearing.
  • The blade can go through teammate's body.
Zombie Scenario
