Shelby's career continued to grow and be successful across film and TV, but at the age of eighteen, Shelby walked into what she thought was another on-camera audition, only to discover it was an audition for the video game Dead Rising 3. She booked the female lead, a zombie-killing badass named Annie, with Tom Keegan directing, and she experienced PCAP for the first time. This shoot changed the trajectory of her life because PCAP combined everything she loved: the long single takes felt like theater, but at the same time it felt like film, with no makeup or lighting to fuss over, just a room to play pretend with other actors. About two years later, with Dead Rising 3 under her belt, Shelby was introduced by her reps to the voice agents she has now been with for a decade, and she began regularly adding VO and PCAP to her work. Despite loving TV and film, the more Shelby worked in voice over, the more she realized it was where she found the most enjoyment. Shortly after, an ADR job confirmed her feelings when it landed on the same day as an on-camera callback. Her on-camera agent asked what really mattered to her, and the question led to an epiphany: she would prioritize her work and hone her skills in voice over rather than film and television. After she made that decision, the work she wanted arrived in force over the years! It was, as she puts it, more real acting than she'd ever had the chance to do on camera, and it let her dive into roles and franchises she never thought she would be a part of. PCAP took her into God of War Ragnarök, Star Wars Jedi: Survivor, and twice to Sweden — first as Soph in Wolfenstein: Youngblood, then back for Horizon Call of the Mountain. In the booth, free from being cast by her appearance, she could be an alien warrior in her forties one day, an eight-year-old boy the next, and the voice of a lot of smart assistants. Among all those roles, she has also found herself in some of the biggest franchises, playing iconic characters such as Batgirl and even Princess Leia in LEGO Star Wars: The Skywalker Saga. It's an honor she can hardly put into words, and one she takes incredibly seriously.

Nowadays, Shelby continues to work through the most fulfilling stretch of her career yet, in the booth and in the volume. Unexpectedly, social media too has now joined her portfolio of work. She joined TikTok during lockdown on a whim, and to her surprise, Good Morning America called to talk about voice acting. What began as a fun way to practice her craft grew into a whole other career she never anticipated. Every day, Shelby hears from curious people asking how to get into this industry, so she uses her platform to give them a peek behind the curtain at how the work is really done, without ruining the movie magic. She is honest about what's back there: there is no such thing as a "good voice"; every voice is the right fit for some characters and wrong for others; and at the end of the day, the job is ninety-nine percent acting. It's a challenging industry that will force you to grow, but as long as you put in the work and sharpen your skills, you can do it. Shelby's ambition is to simply keep growing and to do this for the rest of her life. Building a career of playing pretend, with higher stakes. Putting on different hats for whatever the role requires, just as she would put on different hats while playing with her grandfather all of those years ago.
