Custom Content Development

In addition to developing content based on our own designs, we have also had great success developing content on behalf of brand-holders and publishers.

In the past, we have produced games based on brands from companies such as DreamWorks Animation, MTV and Hasbro.

In 2010 we started working together with Cartoon Network, creating games using their cartoons and characters.
Titles include Ben 10 Alien Force, Ben 10 Ultimate Alien, Generator Rex, Samurai Jack and Johnny Bravo.

Our team of gifted game designers, graphic and pixel artists and sound engineers are able to turn the vision of a game into reality.

Tools and Technology

At Runestone Games we make a large investment in advancing our in-house tools and technologies, which we believe produces a significant reduction in the costs of developing mobile content.

Our unique combination of custom tools and code libraries give us the capacity to deliver foreign language versions across a wide range of handsets at a minimum level of cost. Assets such as graphics, fonts, text and sound are managed efficiently. Ultimately, this means that our games can be bigger and better.

If you are a developer interested in licensing technology from us, or would like us to consult on your development processes, please contact
