The Fallout game series centers around a group of survivors who come out of their fallout shelters and find themselves in the post-apocalyptic USA filled with mutants. The games draw inspiration from 1940s America, and they are heavily influenced by the threat of nuclear war during the Cold War.

Fallout wouldn’t be the first time Purnell has joined a video game adaptation. She voiced Jinx in the highly acclaimed Arcane animated series on Netflix, which earned her an Annie Award for best voice-over performance. Purnell also received praise for her performance in Showtime’s hit drama series Yellowjackets. She has also been featured in films like Zack Snyder’s Army of the Dead and Miss Peregrine’s Home for Peculiar Children.
