Péndulo Studios, S.L.

Péndulo Studios is a game development studio founded in 1994 in Madrid, Spain by Rafael Latiegui, Ramón Hernáez and Felipe Gómez Pinilla. The company only creates 2D point-and-click adventure games. Péndulo's first title was Igor: Objective Uikokahonia (1994) followed by Hollywood Monsters (1997). At a time when other companies were turning away from adventure games, the studio had its international breakthrough success with Runaway: A Road Adventure (2001), which would eventually form a trilogy with Runaway 2: The Dream of the Turtle (2006) and Runaway: A Twist of Fate (2009). The second title was also the first in the series to be taken to other platforms aside from Windows: the Wii and the Nintendo DS. That experiment was however not repeated for the titles afterwards. After finishing the Runaway trilogy, Péndulo revisited its second game Hollywood Monsters with the sequel The Next Big Thing (2011). The team released Yesterday in March 2012. It was their first game that moved away from the typical quirky characters and humour Péndulo is known for. It has a much more darker atmosphere and a twisted plot.
