Developer tools company appMobi launched what it claims to be the first "massively cross platform game" developed using HTML5.

Called Boom Town, it has been released for Android, iOS and Facebook, meaning more than 1.5 billion potential users can access the game.

It was developed by appMobi using its ImpactJs game engine and a single HTML5 code base, with the company touting it as a "tour-de-force of cross platform mobile game development".

The game is a Western-theme town building game.

Boom Town uses appMobi’s 1Touch Universal in-app purchasing technology as well as its appSync to save progress and allow the game to be accessed from another device.

Other features are Facebook integration, leaderboards and badges, analytics tracking and in-game cross promotion.
