[1] She went on to the film school at San Francisco State University, when she was hired as an artist for an Atari game called ElectroCop.

[1] Afterwards she joined Electronic Arts as an animator and artist, doing work on an unreleased title, Bard's Tale 4, and Desert Strike.

[6] Two years after being hired at Electronic Arts, Hennig worked as an artist on Michael Jordan: Chaos in the Windy City.

[1] In the late 1990s, she moved to Crystal Dynamics,[7] where she assisted Silicon Knights in the development of Blood Omen: Legacy of Kain.

[13] It was reported in October 2017, that EA was shutting down Visceral Games and that their Star Wars project was delayed and moved to another studio to allow for "significant change".

[14] Hennig announced the following June that she had left EA in January and started a small studio to explore options involving virtual reality games.

[15] In November 2019, Hennig announced she joined Skydance Media to start a new division there, Skydance New Media, for "new story-focused experiences [that] will employ state-of-the-art computer graphics to provide the visual fidelity of television and film, but with an active, lean-in experience that puts the audience in the driver's seat".

[25] With her work in the Uncharted series, Hennig described the writing and plot as on the "bleeding edge" of the genre of cinematic video games.

[26][27] Hennig has been cited as an example of a successful woman in a historically male-dominated industry, and of how women are taking more important roles within it.
