In the ruthless world of Ninja Gaiden 4, your blade skills are only half the equation. The game’s dual-currency economy—NinjaCoin and Weapon EXP—can make or break your progress, especially on Master Ninja difficulty. Many players get stuck not because of weak combat skills, but because they’re not optimizing how they earn and spend resources.
This complete farming guide breaks down the best ways to stack NinjaCoin and Weapon EXP quickly, manage your spending wisely, and prepare for the brutal endgame. Whether you’re struggling through early missions or gearing up for New Game+, these strategies will keep your wallet and weapon trees overflowing.
Understanding the Two Currency Systems
NinjaCoin – The Universal Currency
Uses: Buying consumables, accessories, and global combat skills for Yakumo and Ryu.
How to Earn: Story progression, side missions, selling unused items, and optional challenges.
Why It Matters: Essential for early upgrades—unlocks critical movement and combat skills that make later encounters easier.
Weapon EXP – Specialized Progression
Uses: Unlocking new combos and abilities in each weapon’s unique skill tree.
How to Earn: Defeating enemies with specific weapons; stylish kills and combos grant bonuses.
Key Tip: EXP is weapon-specific—you’ll need to use each weapon to grow it.
