Select fans of the free-to-play hit mobile game Temple Run can download the sequel starting today. Temple Run 2 features the same type of game play that made the original so appealing to millions but adds a wealth of new content to attract new players.

The biggest difference between the first game and the sequel is that you're in a new world, according to Imangi co-founder Keith Shepherd. He said everything is much richer and vibrant because they leveled up on all of the art to make a more compelling environment.

There are also zip lines as an added element to the game which have the same gestures but you're performing a new mechanic and action. Mine carts can be controlled by leaning left or right and you have to duck down to avoid rafters. There are even new characters in the game, each with their own unique power. He noted that it may seem subtle but it's things like this that their players asked for the most.

The original Temple Run is one of many small publisher success stories. The game was built by three developers and published by Imangi in the summer of 2011. Shepherd said the title has generation millions in revenue thanks to in-app purchases and has been downloaded over 170 million times. It's accessed by 15 million players each day, he said.

Temple Run 2 is now available for download in Apple's App Store and will hitting Google Play on January 24.
