Notes
- The Kunai does not have the pinning properties of other projectile weapons, such as the Boltor or Paris, but will simply throw targets backwards upon death.
Tips
- Make sure to adjust your aim for moving targets.
- When using at a distance, aim above the enemy to adjust for the arc of the blades.
- Using the Pistol Ammo Mutation mod can help regain lost ammo when needed.
- Alternatively, bring along Squad Ammo Restores.
- The Kunai's throwing arc means you can sometimes aim at targets behind cover. Aiming slightly above the cover will result in the Kunai curving downwards onto the target.
- Note that this is extremely situational, as enemy cover is usually too high to take advantage of this.
Trivia
- The Kunai (苦無) were traditionally a multipurpose tool, similar in design to a crowbar or trowel. It could be used for gardening, masonry, and other things. Popular culture has since associated the kunai with ninjas.
- The Despair and Hikou share similarities to the Kunai, they are all thrown secondaries that deal mostly Script error: The function "Proc" does not exist. Puncture damage.
- Update 16.7 (2015-06-04) revealed the Kunai to be a themed-weapon based off the Paris, in the same manner that other themed-weapons like the Akjagara, Aksomati, and Bolto are related to the Tigris, Soma, and Boltor respectively.
