Dengeki Online has a writeup that makes clear of some of the gameplay of the upcoming Wii action game, Tenchu 4, which is set to hit Japanese stores on October 23rd.

There will be an observation mode where enemies will turn red so you will be able to see and pinpoint their location, while also paying attention to sounds coming from both the TV and the Wii Remote speaker to keep your cover. Female lead Ayame is able to seduce targets and lead them to places where she can finish them off or silence them. One of the items at the characters' disposal is a bomb, which can be thrown, placed on the ground, or placed on a target, leading to a fiery explosion.

Tenchu 4 is being published by From Software, and is developed by Acquire. You can check out the official site here Check out the rest of the screenshots over at the source.
