The Ninjaken is a Katana exclusively for Shadow. Unlocked at level 4.
- Due to this guns high mobility, but poor range and damage per second it is best used for flanking unaware enemies.
- Pairing this gun 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 Xian 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.
