One of the surprises at this year's E3 was news that Guerrilla Games was making two new titles, and neither of them are Killzone.
Rigs is a stunningly slick virtual reality sport mech combat game and Horizon Zero Dawn is a bizarre future/past action role-playing title.
In this video, Mark Norris, senior producer at Guerrilla Games, talks us through the trailer shown during PlayStation's press conference. In it, he explains how Aloy, the hunter who stars in the game, uses her speed, cunning and agility to survive.
He also talks at some length about some of the design choices for gameplay.
