Eidos Interactive

Square Enix Europe Ltd. is a British subsidiary of the Japanese video game company Square Enix, originally founded as Domark in 1984.

In 1995, the company was acquired by Eidos plc, being renamed to Eidos Interactive, which would acquire 51% of Ion Storm in 1999 and open Eidos Montréal in 2007. The company would later be acquired by Square Enix in 2009.

The same year it was founded, Eidos Montréal began work on a Deus Ex project that would be released in 2011 as Deus Ex: Human Revolution under Square Enix, later developing Mankind Divided.

In August 2022, Square Enix sold several of Square Enix Europe's assets, including the Deus Ex intellectual property, to Embracer Group AB.
