Ubisoft partnered with Amblyotech to come up with the breakthrough treatment for lazy eye, which it said is also entertaining.

Paris - Gaming developer Ubisoft said on Thursday its action-adventure sensation Watch Dogs is helping propel revenues, which soared to 360-million euros in the first three months of its financial year starting April.

The French company, whose sales were boosted by the popularity of the new game on XBox, Playstation and PC, posted an increase of 374 percent between April and June, a statement said.

Watch Dogs was the main driver of that income. The game has sold more than eight million copies since its launch in May.

The title - launched as a contender to Rockstar Games' Grand Theft Auto series - features a highly-skilled computer hacker who seeks revenge for the death of his niece. It cost 70-million euros to make. - Sapa-AFP
