Watch Dogs has sold in over 8 million units, Ubisoft has announced. The numbers represent units sold in to retailers rather than sold through to consumers.

Nevertheless, the game's success helped Ubisoft's Q1 sales grow by 374 per cent year-on-year, reaching €360m (£286m) for the first quarter. In comparison, the firm managed just €76 (£60m) during the first quarter of last year.

"The success of Watch Dogs and the quality of our games portfolio presented at this year's E3 highlight our strategic positioning as well as our continuous drive for innovation, and affirm our long-term approach," said CEO Yves Guillemot.

"Watch Dogs is now well positioned as a major franchise and we will be able to replicate and build on its success in the coming years. Its sales performance testifies to Ubisoft's expertise as a creator of blockbuster brands. That expertise enables us to stand out from our competitors at the beginning of each console cycle and therefore to reach a new dimension."

Watch Dogs broke Ubisoft and industry records upon its launch in May, becoming the fastest-selling game in Ubisoft history and the industry's fastest-selling new IP.

A Wii U version is due to release this autumn.
