There are two main gameplay modes in "DBVR". The first one is action-adventure. The player navigates a polygonal character (there are several controllable characters in the game beside Tatsuya and Kaoru) over pre-rendered backgrounds. When approaching an enemy from a suitable angle, a red cross-hair will appear, at which point the player can shoot at the enemy to kill it. There are objects such as healing kits or keycards scattered around. There is also a map that allows the player to investigate locations in a different order.
The other mode is Illusion's trademark 3D "seducing simulator". Players interact with a large 3D model of a girl by selecting an appropriate icon (touch with a hand, kiss, etc.) and a part of the girl's body or garment. Some actions can be executed in a very precise manner. For example, if one places a hand on the girl's breast, they will be able to stroke it in different directions, squeeze it, etc. Those movements are displayed on the screen as real time 3D animation.
