Ahead of the release of Alien: Isolation, this special edition of Tech Weekly looks at the resurgence of the horror genre in computer gaming

This week Guardian games editor Keith Stuart takes over the pod to explore the recent release of a new generation of horror genre computer games.

Keith is joined by Leigh Alexander, a writer on gaming and games culture, to discuss the evolution of horror games over the last two decades and more and why indie games makers are returning to the genre.

Also we meet Dan Pinchbeck from the indie games studio The Chinese Room creators of the award winning Dear Esther and the soon-to-be-released Everybody's Gone to the Rapture. Dan discusses the creative opportunities that the horror genre offers and why there is so much innovation in this area.

Finally Keith meets actor and producer Sigourney Weaver ahead of the latest Alien game Alien: Isolation.

Sigourney discusses her role in voicing the character of Ripley for this incarnation of Alien and why she thinks computer games are the ideal place for Alien characters to develop.
