Mozilla (the people behind FireFox) have recently announced in their blog that they have teamed-up with Epic Games to port the Unreal Engine 3 to web browsers.
Mozilla credits their highly-optimized Javascript for allowing this technology to come into fruition. This allows game developers to port their existing Unreal Engine 3-based games to work with all browsers supporting Web-GL.
We are working with premium game publishers such as Disney, EA and ZeptoLab who are using the same technology to bring performance optimizations to their top-rated games.
