Zombie Infection
  • A Stamper can perform a Coffin Jump by standing on the iron maiden and stabbing it repeatedly (five times to be exact) while jumping. You must get it fast because the coffin will not last long. With the cost of some health, the Stamper will be thrown as high as the way to the blue containers in Assault or from the alcove to the clifftop in Militia, depending on the height of the jump. This technique can be done by any zombie types except Heavy zombie, Deimos and Ganymede since they are heavy-type zombies.
  • Stamper's coffin can deal damage to nearby players including the one who deployed it. Anyone with low health can be killed by it, counting as an addition or reduction in the score depending whether a teammate or human was killed. Killed humans can not respawn, they would have to wait as if they had committed suicide.
Zombie: The Union
  • The Stamper has 2500 (3000 with Strong Lifepower) health points and 250 (300 with Strong Lifepower) armor points.
  • The Iron Maiden used to last for about 8 seconds, but now it only lasts for 5 seconds.
  • Stamping delay used to be 10 seconds but now it is 20 seconds.
  • Stamping ability deals damage to surrounding enemies.
  • If a Stamper is caught on "Stun Self Destruct", they can use their ability to instantly counter it.
  • Whenever the player deploys the Iron Maiden, they will not be able to move for the time being.
  • The Hardening skill is aimed to maximize your probability of survival.
  • It takes 5 stabs from the stamper to destroy the Iron Maiden in Zombie modes, while it takes 8 stabs in Zombie Union to do it.
