Shadow of the Ninja/Sea Port

Stage 1-1
Just move forward, killing enemies and getting used to controls. First baddies you encounter will be three sailors. Take shurikens from the first container you see – it will make the boss battle easier. When you climb up, you will meet robotic beetle.

Jump down and meet another one. Since avoiding it is a little bit harder than destroying, kill it. Go further to meet monkey and another sailor. You will find kusarigama in the next container. It’s better for one player to take it if you’re playing with your friend.

Go further to see the railing and two robotic beetles: one on the railing, and another one on the deck. The upper one guards container with healing potion. After that you will meet another beetle and the last sailor in the game.

Move forward to meet the first boss.

Stage 1-2
Go right until you meet rugby players and women with whips. It’s usually easier to ignore rugby players for now, and it’s better (and much easier with kusarigama) to get rid of whipping women. When you jump off the crates, you’ll encounter another woman with whip.

After that you’ll have to climb up. There is a kusarigama in a box near the wall. When you’ll be climbing, remember, that rockers are much easier to avoid that to destroy, and destroying missile launchers won’t give you any benefits. There’s a container with katana near the wall. Woman with whip will be waiting for you on top. She sits next to the pit, so she’s quite tricky to fight. You can either destroy her with kusarigama over the pit, or you can destroy the rightmost rocket launcher and climb up from the right of that woman.

The rugby player will appear, and he’s pretty annoying. Better get rid of him, since he can push you down to a pit or to any of two women with whips at the end of the stage.

Stage 1-3
Now you are in some sort of warehouse with giant wheels. Get rid of the rugby player (he cannot push you into another enemy, but he can push you down to the bottomless pit) or run past him and jump on a platform. You’re safe from that enemy on the platform, sine he can’t jump on it and will always fall down through it. After a wheel with platforms you will find a sword. After it there will be another wheel with platforms and a sniper. Luckily, there’s plenty of room for maneuvering.

When you encounter the second sniper, get ready to act quickly. See the wheel with platforms after him? When the platform appears, the monkey will be sitting on it. If you’re quick enough, you can miss the monkey. After that you will encounter another wheel with platforms.

The next step is a little bit tricky. The lower wheel has two platforms, while the upper one has only one. You need to jump on the lower platform when there is one on the upper wheel. If you jump on the platform while there is nothing on top, you’re very likely to fall down instead of going forward.

Take the healing potion from the container, beat the sniper and leave the area to fight the boss.

Stage 1-4
Fight the second boss.
