Sam & Max Save the World is a graphic adventure video game developed by Telltale Games. The game was originally released as Sam & Max: Season One before being renamed in early 2009.
Save the World was developed in episodic fashion, comprising of six episodes that were released for Microsoft Windows over the course of late 2006 and early 2007. The episodes were initially distributed online by GameTap and Telltale Games themselves, although the later retail releases of the game were published by The Adventure Company and JoWooD Productions in North America and Europe respectively. A Wii port of the game was published in late 2008, and a Xbox Live Arcade version for the Xbox 360 was released in mid 2009.
