D3 Publisher has shared a new gameplay trailer for Omega Labyrinth Z.

Featured above, the new gameplay trailer shows off the game’s returning item-discovery mechanic, which has you rubbing a phallic-shaped object in between the girls breasts, growing it until it explodes in a big white cloud.

As this game is an upgraded version of the original, even the breast-rubbing identification mechanic has been expanded – quite literally in fact.

The game’s Z-cup breasts are fully rendered in 3D with physics, you see that towards the end of the gameplay. There’s even a mode where two girls straddle a large, phallic object until it explodes too.

Omega Labyrinth Z is launching for both PlayStation 4 and PS Vita in Japan on July 6th.
