Ninja Gaiden II: The Dark Sword of Chaos

Side-scrolling action game where ninja Ryu fights through enemy-packed stages to stop Ashtar, a dark lord manipulating events from below. You'll wall-climb, slash with katana, and deploy ninja arts—fire wheels, shadow clones, invincibility—while dodging projectiles and platforming hazards. Enemies respawn constantly, forcing you to keep moving. Boss fights cap each stage, testing pattern recognition and reflexes. The game leans on precise jumps and quick weapon swaps more than its predecessor, with tighter corridors and aggressive enemy placement. Ryu can now summon shadow duplicates that mirror his attacks, adding a risk-reward layer to combat. Expect frequent deaths while learning enemy rhythms. It's unforgiving but fair if you memorize spawn points and attack windows.
