Video: First glimpse of Unreal Engine 4 running on a web browser

Epic's high-end engine coming to web browsers

Epic Games has ported its next-gen Unreal Engine 4 tech to run inside web browsers without the need for a plugin.

Epic and Mozilla have collaborated to get the engine running in Firefox, and released the video below offering the 'first glimpse' of UE4 on a browser with no plugin. The video shows off the Epic Soul tech demo.

Epic Games founder and CEO Tim Sweeney said, "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.

"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."

The engine runs on the browser using asm.js, 'a supercharged subset of JavaScript pioneered by Mozilla'.

"Any modern browser can run asm.js content, but specific optimizations currently present only in Firefox, ensure the most consistent and smooth experience," claims Mozilla.

"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.

UE4 was revealed as a high-end engine targeting next-generation games hardware, but we great scalability. That scalability was recently demonstrated when Epic revealed the engine running on NVIDIA's new Tegra K1 mobile chip.

Epic and Mozilla will show off more UE4 in browsers at GDC next week.
