NINJA GAIDEN 3: Razor's Edge

Like above trophy, this will be very tough trophy to get. There more enemies in tight areas which forces you to see the game over screen quickly. When there's plenty of determination then this obstacle can be conquered. Trophy unlocks after clearing Ultimate Ninja difficulty.

Tips:
1) Use ultimate techniques every chance you can get.
2) Abuse izuna drops on lesser enemies that can be dropped.
3) Save any your Ninpos until you're health meter is red.
4) If surrounded by a lot of enemies, be sure to use (SOB) steel on bone execution combos as much as possible
