Which studio developed Star Wars: Empire at War?

Star Wars: Empire at War was developed by Petroglyph Games.

Released in 2006, Empire at War is a real-time strategy game set during the Galactic Civil War. Petroglyph designed the game around both planetary ground battles and large-scale space combat, letting players manage fleets, construct units, capture worlds, and pursue campaign objectives for either the Empire or the Rebel Alliance.

The game was one of Petroglyph's early major projects. The studio was founded in 2003 by former Westwood Studios developers, including Joe Bostic, Michael Legg, and Steve Tall. For Empire at War, Petroglyph created the Alamo 3D game engine, which supported the game's strategic galaxy layer and its tactical battles.

LucasArts published the original game, while Aspyr handled the Mac OS X release. A 2006 expansion, Forces of Corruption, added the Zann Consortium as a third faction. The developer is sometimes confused with Raven Software or Pandemic Studios, but those studios worked on other Star Wars titles, including different first-person shooters and action games.
