Ninja Gaiden II: The Dark Sword of Chaos (NES) - Act III
The area is dark but will flash every now and then, so be sure to time your jumps to cross over holes carefully. Flames will appear at random spots, but should be easy to take out. Some walls have blobs that will switch sides or even release fireballs. Expert knife men will come around at certain spots, so be sure to be on a lookout for that. Once you far, enter the castle and the blackouts will subside. Some spots have axe throwers and diving ninjas. After climbing ladders twice, there will be big spiders shooting fireballs. Climb twice more and you’ll encounter an elite guard with a shield and flaming boomerang. Defeat a few skeleton warriors and climb once more to battle against Funky Dynamite. Funky Dynamite will move in the air, releasing fireballs and chunks of explosives. Defeat this boss and Ryu will witness that Irene is safe and sound, but Ashtar will arrive and cast a stunning spell on Ryu. As Ashtar prepares to make his move, a gunshot will stop him, which seems to be the man Ryu saw earlier. Ashtar will leave with Irene hostage.
