He has also consulted on general game design for Microsoft, Electronic Arts, Activision, Midway Games, and others. More recently, Whitta was tapped to oversee the narrative development of Telltale Games' episodic video game adaptation of The Walking Dead, while writing its fourth episode. Though he left Telltale after completing the first season, he will return to help Telltale complete the fourth season of The Walking Dead, expected for release in 2018.
