Ninja Gaiden

If you upgrade the dragon sword 3 times you can unlock it's second charge attack. I call it the "Spin Splitter". To do this attack, you have to move the left analog in circles. While doing that press and hold the y button to charge it, leave y and there you go, the spin splitter.

As you know Alma is super strong,and there's a weakness for her,the Vigoorian Flails. With this weapon you can still attack her even when she is in the air.

Successfully complete the game under the normal difficult setting. Then, hold L while selecting the "New Game" option at the opening menu. Successfully complete the game under the very hard difficulty setting to unlock yet another costume.

This is pretty simple. In chapter 6 once you get under the monastery. There's cave that has a very large number of bats in. Now the first time you are in the cave there these wierd red flying mutants. But after you beat the skeletal dragon. you'll see him in a frozen state. Anyways after you beat him. That cave becomes full of bats. Have your normal shuriken equiped. Kill two bats with the shuriken. And then press and hold the Y button to asorb the two yellow essence into ryu sword. After you have asorbed the two essence into ryu's sword release the Y button to deliver ryu's ultimate attack. This results into each bat leaving a huge yellow essence gather them. Leave the cave then enter the cave again. Then this trick all again. Keep repeating this trick for about an hour and your will reach the max cash ryu can carry witch is 99,999.

Some players tend to have trouble with this boss mainly because of his massive power on attacks. Basically, he's equipped with a gigantic electric gun, that shoots out blasts of electrical charges in small intervals. What you should do is keep distance between him and yourself. Keep running in circles, but DO NOT jump (makes you an easier target). You can try rolling, but keep running in circles until he fires about 5 laser blasts. Suddenly, his gun will discharge, and it'll be jammed for a few seconds. Quickly sprint in, and lay down a few power slashes. If you want, you can also cast Ninpo magic to assist in causing more damage. Just repeat this strategy, and keep retreating/approaching. If you stay close too long, he'll grab you, and shoot you point blank with the weapon. Also, try to keep several potions on hand when facing him. You might take a few hard hits along the way. Aside from that though, he's not as challenging when compared to other bosses faced.
