Dead Or Alive is a celebrated series of breast physics simulators. To enhance the movement, bouncing, pitch and yaw of the breasts, the developers crafted a fighting game wrapper. In answer to the puzzling question of how sand affects breasts, two titles in the Dead Or Alive series were set at beach volleyball tournaments.

Research generated by the series as lead to important developments in the breast community such as knowing how far to stand back to avoid getting smacked in the head by a giant breast.

Next up for the series is the NASA-funded Dead Or Alive In Space and DOA Earthquake.
