SOFTWARE DEVELOPER Mozilla has shown off a video of the Unreal 4 game engine running in Firefox without looking like a stop motion cartoon.

A two minute video of the engine in web browser action has been uploaded to Youtube. In it the engine is shown running without third party assists.

"This video provides a sneak peek of Epic's Unreal Engine 4 running in Firefox at near-native speeds," it says. "Game demos shown include: Epic's Soul and Swing Ninja running on the Web without plugins."

The video shows the games running smoothly. According to a Mozilla blog post it is the result of close work between the two outfits, and the use of asm.js, which it called a "supercharged subset of Javascript".

"This technology has reached a point where games users can jump into via a web link are now almost indistinguishable from ones they might have had to wait to download and install," said Brendan Eich, CTO and SVP of engineering at Mozilla.

"Using Emscripten to cross-compile C and C++ into asm.js, developers can run their games at near-native speeds, so they can approach the web as they would any other platform."

This is not the first time that Mozilla and Unreal have danced, and last year they showed off Unreal 3 in action on the Firefox web browser.

"We were blown away by what this Mozilla-pioneered technology achieved with Unreal Engine 3 on the web, so we had no hesitation in working with Mozilla to port Unreal Engine 4," said Tim Sweeney, founder and CEO of Epic Games.

"We believe the web has a crucial part to play in the future of game development and deployment, and Mozilla has proven it is the catalyst to make this happen."

You can see it in action in the video below or at the Games Developer Conference (GDC) next week. µ
