Epic unveiled today a fully-functioning Unreal Engine 3-powered demo game that is playable completely inside all HTML 5 compatible web browsers.
The game, takes advantage of HTML 5, WebGL and JavaScript to run in modern browsers such as Firefox and Chrome without requiring any extensions or plugins.
"With Mozilla's latest innovations in JavaScript, game developers and publishers can now take advantage of fast performance that rivals native while leveraging scale of the Web, without the additional costs associated with third-party plugins," says Mozilla. "This allows [developers] to distribute visually stunning and performance intensive games to billions of people more easily and cost effectively than before."
Mozilla and Epic finished porting Unreal Engine 3 to HTML 5 in four days only by taking advantage of C++- tool Emscripten and the Mozilla-backed JavaScript subset asm.js.
