Ninja Gaiden (NES)/Act 1

Stage 1-1
Stage 1-1 is easily completed.

The first two lanterns each provide 5 units of spiritual power. The next provides 10 units, which should be more than enough to last through to Stage 1-2.

The most important item within stage 1-1 is the jump and slash. It's location is shown in the image, and can either be reached by a damage boost (by jumping into the enemy), or through a safer and longer route by jumping onto the wall and sign.

Stage 1-2
Stage 1-2 is a fight against Barbarian. He can be instantly killed with the Jump & Slash, by jumping at point blank and instantly starting the slash.

If you cannot use this attack, he is still easily defeated. His main axe swing is easily ducked, and you can swing your sword to inflict as much damage as possible.
