The Walking Dead: Survival Instinct is a single-player first-person shooter video game developed by Terminal Reality and published by Activision. It is based on The Walking Dead television series, in contrast to the video game by Telltale Games, which is based on the comics. The Walking Dead: Survival Instinct acts as a prequel to the TV series; it is set in the Georgia countryside and focuses on Daryl and Merle Dixon as they make their way to Atlanta during the early days of the zombie apocalypse.
