Ubisoft has partnered with Microsoft's Internet Explorer to release a demo version of Assassin's Creed Pirates, built using HTML5 and playable in web browsers.
The game is created using Babylon.js, an open-source framework that allows creators to build titles using HTML5 and WebGL.
Ubisoft studio manager Francois Bodson said: "We wanted to bring a taste of this game to the web. It was a challenge and a technical demo for the mobile application on Windows 8 and Windows Phone 8."
Unlike the version previously released for iOS and Android devices, the browser version of Assassin's Creed: Pirates is entirely based around racing your ship around the seas.
Priced at £2.99, the iOS and Android apps let players explore the Caribbean, upgrade their boat and recruit new crew members to aid them in real-time naval battles.
The Assassin's Creed Pirates web demo is available to play for free in five languages worldwide. Check it out here.
