Eidos has confirmed to GamesIndustry.biz that it has closed its mobile gaming studio in Manchester, with 14 redundancies.
"As a company we need to focus our efforts on high-quality titles that will deliver long-term franchise value, and in these incredibly challenging and competitive times we need to pro-actively manage our cost base," said the company.
"This decision was a difficult one to make and we would like to thank these employees for their hard work and we wish them well in their future careers."
Eidos acquired Rockpool Games, as it was then known, in February 2007, along with its two sister companies Ironstone Partners and SoGoPlay.
The publisher picked up the teams to continue its push into casual and mobile gaming, which at the time the company believed were "consistently growing markets".
