NINJA GAIDEN II

Mainly a boss guide.

Sub-Boss: Genshin
After you've finished taking out the engines, you'll return to the main hold and face Genshin again. It's largely the same fight with the addition of ten Incendiary Shuriken Ninjas alongside him this time. You need to move quickly and take out the ninjas while staying on the move and out of the air to avoid Genshin. Once you've taken all of them out, you can turn your attention to him and bring him down the same way that you did in Chapter Two. Do try to avoid getting too far away from him this time because he'll throw Incendiary Shurikens at you as he closes the distance.

I found a technique for the *second* and final boss (the fire dinosaur boss) that makes this fight pretty easy. Aim for the side of its head with you attacks or his hind legs but the head is best. Especially attack with all 30 of your *Incendiary Shurikens* at its head when you have a clear shot. This does a lot of damage and you can easily get his health down. At about 25%, he starts to spam balls of fire, so use your remaining Shurikens to finish him off again at the head.

With about 10% health, he falls to the ground and you finish him off at his head with your sword.

Avoid his round ball attack and his fire ball mode by simply running and jump at about a 45 degree angle. He won't touch you.
