Mission 5--Amagai Castle
Amagai's castle seems abandoned by people but is populated by strange mechanical robots. Use haste but be careful. You must rescue Princess Kiku.
Rescue the Kidnapped Princess!
Objectives: Stay alert for traps. Press your back against walls to open trap doors. The enemy is not human.
Quickly dodge to the left or right to avoid the mechanical guard patrolling at the end of the wall. Wait for the guard to move away, then sneak up behind it and perform a quick stealth kill. Look up and to the right. Use the grappling hook to ascend to this upper level. Watch your step and don't fall into the lava below. Leap across to the adjacent ledge, then turn left and leap down to the path on the far side of the room.
Cross this path to the right and turn right to spot another upper path. Use the grappling hook to reach this upper path. Leap to the far bridgelike surface and listen carefully to the guard patrolling below. Peer down and wait until the mechanical guard moves away and to the left. When it does, drop down and perform a stealth kill. Wait for the guard to be along the left side when you drop down. If you drop down along the right wall, a trap activates and impales Rikimaru with spears. Don't move back into this area after killing the guard.
Move through the passage beyond the dead mechanical guard. Floor traps populate the next hallway. Jump over this path to avoid the traps. If a trap does activate, jump forward quickly to avoid falling to your death (and to avoid a required level restart). Hug the left wall and peer inside the room to the left. There's a tough mechanical enemy inside. These guys fire projectile weapons and perform a devastating spin maneuver that can inflict significant damage, particularly if you're trapped in a corner.
Wait for this creature to face away from you. There's a second danger nearby. The doorway is rigged with a trap (note the spikes at the top of the doorway). Trigger the trap by moving in and back out of the doorway quickly. When the spikes are rising back up to the doorway's top, enter the room and sneak up on the creature. Perform a stealth kill if possible.
