The DualShock 4 speaker implementation is yet another Housemarque game that makes some of the best usage of the feature by producing voice - overs in a tone reminiscent of Resogun; indicating when and which type of power - up has been collected; when the
strength of a weapon has been maximised; an increase in
multiplier has been earned; all
humans in an area have been saved; when shields have been deactivated following a collision with an enemy; and more besides.
