Mission 2--Gohda Castle
Nasu was killed by another assassin. This truly bothered Tesshu. He could not sleep well that night. Tesshu's curiosity regarding Gohda's ninjas escalated because Zennosuke kept telling him to forget about it since crossing swords with the Azuma ninjas was the same as suicide. But Tesshu was still angry that he could not collect his fee because Rikimaru got to his target first. Ignoring Zennosuke's advice, Tesshu sneaks into Gohda's castle to find Rikimaru and prove to himself that he is the better assassin.
Teach Rikimaru a Lesson!
Objectives: Stay in the shadows and trust your ki. Rikimaru is far inside the castle. Stay hidden and do not alert the guards.
You're currently underneath a structure, and a guard lurks just outside. The quick way to the castle is under this structure. Move through the crawl space and exit near a path that takes you toward the castle. An alternate route lies within the halls outside this structure. If you recall Rikimaru's mission, Hamada's room contains a passage into the castle that bypasses a lot of ground. You'll find it on the right side of the map.
If you do explore these rooms, proceed to the southern edge of the map and look in the room to the left (when Tesshu enters this area). You'll find a health power-up and a box containing throwing needles. But there's another reward nearby. Look in the right corner of this room for a higher room above. Grapple up into the room and grab the two boxes of money. Guards lurk throughout these rooms, so move with extreme care and caution if you're striving to leave as many guards undisturbed as possible.
