Ashtar uses this opportunity to hatch a new plan to plunge the world into darkness.

The ninja, Ryu Hayabusa, hits the trail to destroy all manner of vile creatures entering the world while fighting his way to destroy Ashtar, his Dark Sword of Chaos, and whatever else is behind the evil.
Ninja Gaiden II: The Dark Sword of Chaos is a fast paced, side scrolling action game in the tradition of the original Ninja Gaiden game.
Ryu is a ninja who can run, jump, and slash with his ninja sword.
He can also attach to vertical walls and climb up and down, which is an ability missing in the previous game.
Powerups are hidden everywhere throughout the levels.
These powerups include fireballs and ninja stars as before; a unique new powerup is the ninja shadow.
Ryu can collect up to 2 ninja shadows that follow his every movement and use the same weapons at the same time that Ryu strikes.
Ninja Gaiden II tells its story through liberal use of cinematic scenes interspersed between the action levels.
Different levels feature a variety of environmental interaction; e.g., one level has Ryu on a high mountain where snow is falling fast and the wind is blowing hard.
The shifting direction of the snowfall indicates how the wind is blowing and Ryu has to fight against the breeze.
In a night level, much of the environment is dark and is illuminated only sporadically by flashes of lightning.
About Nintendo Entertainment System
The Nintendo Entertainment System (1983 in Japan, 1985 in the West) revived the North American video game industry after the 1983 crash and established conventions — cartridges, licensing seals, save systems — that shaped the industry for decades. NES collecting is one of the most established retro markets: common titles remain cheap, but a well-known handful of low-print-run games (many from smaller third-party publishers) are among the most expensive video games in existence.
Gamevaro tracks AO for Nintendo Entertainment System with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding AO to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This NES release dates back to 2016.

Rarity & condition
Only a handful of market sales have been tracked for AO, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Nintendo Entertainment System titles.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
