Tecmo is bringing SIXAXIS boob jiggling to upcoming PS3 title Ninja Gaiden Σ II. Shake your controller, and you can shake character boobs.
The clip below shows just how exactly players and jiggle Rachel's breasts. Ninja Gaiden producer Yosuke Hayashi shows the mechanic in action while at an event in Spain.
Wonder how this will work for Ninja Gaiden ninja Ryu Hayabusa... Hrm, hrm.
