In Mortal Kombat for the PS Vita, there is an interesting new Augmented Reality mode that you can play in, that switches the backgrounds of your fights to every day scenes, like a kitchen, or a busy street.
To enter Augmented Reality mode, open up Practice Mode and hit Triangle to enter Arena Select. With any arena selected, press and both L and R buttons at the same time. You’ll hear Shao Kahn’s laugh if done correctly.
