Ninja Gaiden (NES)/Act 2

Stage 2-1
2-1 is the first stage to have bottomless pits but otherwise, it is the same as 1-1. Bats are the main annoyance here because they immediately regenerate after killing them. They do not regenerate if you leave them alone, however.

Stage 2-2
Learn to attack while jumping foward as you'll need to do that a lot in this section. The windmill throwing star is useful here but try to keep the jump-and-slash technique if you can for this and 2-3. When you get the art of the fire wheel start. Moving. Fast.

One easy way to get through this(and other areas) is to increase the enemy's movment. Some of the humanoid enemies turn around when reaching a cliff but imediately turn when touching the edge of the screen(unlike many other games). By moving foward slowly, you can increase their movement path, allowing you to safely reach the plaforms taking little or no damage. Just be sure to use special abilities on the priests before jumping.

Stage 2-3
Bomberhead's weapon is slightly longer than Barbarian's but has a similar of attack. The jump-and-slash technique takes half of Bomberhead's life, but with timing you can defeat him by using it only once.
