The Ninjaken is a Katana exclusively for Shadow. Unlocked at level 4.
- Due to this swords high headshot multiplier (which increases backstab damage) it is extremely effective when used on an enemy from behind.
- Pairing this sword with a weapon with high weapon swap speed, like the Tornado, or Typhoon will improve your ability to deal with enemies at range.
- Using the Vampire perk allows you to stay behind enemy lines longer, because whenever you kill an enemy with either your Knife, or with the Ninjaken you will be refilled back to full health.
- Veteran Ninjaken
- Tiger Ninjaken
- Diamond ore Ninjaken
- The Ninjaken uses the Shinobi's old model instead of it's own sword model, making the game technically have 2 Shinobis and no Ninjaken.
