New Grand Theft Auto V footage has been released via a Rockstar 'Epsilon' screensaver.

Viral marketing kicked off on the Take-Two owned website for Epsilon - a fictional religious cult across a number of GTA games - last year alongside a related Twitter account.
"The cult first emerged as a teaser site for Grand Theft Auto: San Andreas and [was] later referenced numerous times on radio stations and by pedestrians in the game itself," according to the GTA Wikia.

"The cult is an obvious scam, intended to gain money by brainwashing its followers into paying large sums of money, parodying the real life Church of Scientology."
