Actua Pool was developed by Gremlin for PlayStation and Windows in 1999. The game was also released under the name Pool Shark. A sequel was developed in Europe in 2004 for the PlayStation 2 and Windows under the name Pool Shark 2 by Blade Interactive. It was not a part of the Actua series as the series had ended years prior, and Gremlin had closed. In 2007, a port of Actua Pool was released for the Nintendo DS, named Underground Pool in North America.
