Following a path already marked out by indie studios, Glu has announced it's taking key titles in its library to the Chrome Web Store, starting with Gun Bros.

The game, which already boasts 13 million downloads on iOS and Android, will be the first of four social games making their way to Google's platform in 2011, including Contract Killer, Big Time Gangsta and Bug Village.

"Google Chrome offers another powerful platform for Glu to bring great social gaming experiences to global audiences," said CEO Niccolo de Masi.

Chrome Web Store, though restricted to HTML5 equipped web browsers, passed 17 million downloads in May and can call on a potential userbase of 160 million.

"We are delighted to be launching one of the first games that support microtransactions on the Chrome Web Store and look forward to bringing additional Glu games to this growing platform," de Masi added. 

Indeed, in-app purchases are an increasingly important facet of Glu's business, with volumes rising 32 percent from Q1 2011 during the firm's most recent quarter.
