Ok, this has to be one of the most obvious Real Life locations from Overwatch, welcome to Santorini, Greece or as you may know it.... Ilios!
The island of Santorini, located in the southern Aegean Sea, is immediately recognizable thanks to its whitewashed walls and piercingly blue rooftops. Overwatch's Ilios map isn't the only time that Santorini has found its way into a multiplayer shooter; it was also a bomb defusal map in Counter-Strike: Global Offensive.
