How to Unlock All the Weapons in Ninja Gaiden 4

One of the enduring hallmarks of the Ninja Gaiden series has always been its deep, diverse arsenal. Few action games empower the player to master so many distinctly unique fighting styles, and Ninja Gaiden 4 (NG4) proudly continues this lethal tradition. While the new protagonist, Yakumo, may not wield as many distinct blades as Ryu Hayabusa did in Ninja Gaiden 2, every weapon he receives is polished, versatile, and feels uniquely devastating.The core innovation in NG4’s combat system is that nearly every weapon features two distinct forms: a base form and a powered-up Bloodraven (or Gleam) state. This dual-identity mechanic effectively doubles the potential moveset for each piece of gear.Here is a full breakdown of how to unlock every weapon in Ninja Gaiden 4 and what makes each one a masterclass in lethality.

Ninja Gaiden 4: Unlock All the Weapons

Yakumo’s Primary Arsenal

Yakumo's core weapons are unlocked through main story progression and are designed to provide a balanced array of options, from speed andprecision to brute force and crowd control.

Takeminakata (Twin Blades / Tachi)

• How to Unlock: Available from the beginning of the game.
• The Forms: This is Yakumo's starter weapon and his most balanced tool. In its default state, it is a pair of dual katanas characterized by quick, accurate slashes perfect for close-range combat and initiating combos. When transformed into the Bloodraven state, the blades merge into a single, longer Tachi. This provides excellent mid-to-long-range reach and can even be cast forward as a ghostly projectile attack.
• Why It’s Unique: The Takeminakata excels at being flashy, fast, and versatile, making it an excellent choice for new players to master the game’s core mechanics.

Yatousen (Rapier / Drill)

• How to Unlock: Complete Chapter 3 – “Phantom Pleasure Quarter.”
• The Forms: The Yatousen is the game’s quintessential elite-killer. Its default form is a rapier, emphasizing precise stabs, counterattacks, and single-target lockdown.When the Bloodraven form activates, the rapier morphs into ahigh-powered drill. This drill is phenomenal at shattering enemy armor and rapidly chewing through the health bars of major opponents.
• Why It’s Unique: While it can struggle with large groups of lower-tier enemies, the Yatousen is indispensable for tearing apart bosses and heavily armored elites.

Magatsuhi (Staff / Hammer)

• How to Unlock: Complete Chapter 7 – “Altar of the Mountain God.”
• The Forms: The Magatsuhi begins as a staff, offering long reach, fluid combos, and superb crowd control, similar to Ryu’s classic Lunar Staff. In its Bloodraven form, it transforms into an enormous hammer. This massive tool sacrifices attack speed for raw, destructive brute force. Hammer strikes can instantly break an enemy’s guard or send them flying across the screen.
• Why It’s Unique: This weapon is the ideal choice when you need wide-area damage and guaranteed guard breaks against multiple foes simultaneously.

Kage-Hiruko (Mechanical Arms / Assassin’s Tools)

• How to Unlock: Complete Chapter 10 – “Bounding Spirits.”
• The Forms: This is arguably the most dynamic and versatile weapon in Yakumo's arsenal. In its base form, it uses large shuriken as blades for melee combat while allowing Yakumo to rapidly throw smaller shuriken as projectiles. The Bloodraven state unleashes mechanical arms that stretch out with lightning speed, drastically increasing attackrange and allowing for fashionable, high-mobility combo chaining against mobs.
• Why It’s Unique: The Kage-Hiruko fluidly bridges the gap between melee and ranged damage, making it a versatile and incredibly fun tool for slaughtering large mobs.

The Legendary & Ultimate Blades

These weapons are tied to either specific character progression (Ryu) or the game’s toughest challenge content.

True Dragon Sword (Ryu Hayabusa)

• How to Unlock: Automatically acquired when you play as Ryu in Chapter 14 – “Unholy Descent.”
• The Forms: Ryu’s signature sword returns, feeling just as deadly, quick, and perfectly balanced as fans remember. The Gleam Mode functions as Ryu's equivalent of Bloodraven, providing a handful ofunique moves and high-damage, shining attacks that elevate him to analmost unstoppable state.
• Why It’s Unique: It is the weapon that embodies the series’ legacy—a masterwork of balanced damage, speed, and iconic style.

Dark Dragon Blade (Ultimate Weapon)

• How to Unlock (Transient): Found temporarily in Chapter 19 – “Ebon Wings.”
• How to Unlock (Permanent): Successfully beat all Boss Trials (on any difficulty level, including Hero).
• The Forms: This is Yakumo’s definitive ultimate weapon. Its moveset is similar to the Dragon Sword, but it incorporates heavier, darker, energy-based attacks. When activated, the Dark Gleam form boosts its damage even further and extends its attack range.
• Why It’s Unique: The Dark Dragon Blade offers raw, maximized offense. While it vanishesafter the story’s completion, the incentive to prove your worth byconquering the rigorous Boss Trials is the only way to lock thisdevastating blade into your arsenal forever, rewarding true mastery ofthe game.

With these weapons in hand, you have everythingyou need to experiment, master every fighting style, and define your own lethal path through Ninja Gaiden 4. Which blade will you master first?
