Our March 2009 tech demo of Duality ZF, our dual play Xbox 360 2D shooter:

Duality ZF, showcasing survival mode and dual play.
(Note:  Ground animations are disabled.)

Survival mode is a one-life score run, only one of six game modes in Duality ZF.  Dual play is one player controlling two fighters at the same time.  One only player is playing in this video preview.
