Biko 2: Reversible Face

It is a Japanese 3D stalking simulation. The player controls a Japanese man who stalks pretty girls. The game starts in "adventure mode" where the main character is looking for objects that he may need later.

When he sees a girl that he likes, he attempts to follow her through the city, trying not to alert her about his presence and not to lose her at the same time.

After the player successfully pursues the girl through several levels, he finally runs her down and is presented with a number of CG images, animation or an interactive 3D rape scene.
