Seifert in Her Story (2015)

In 2015, Seifert was cast in the video game Her Story, a crime fiction video game by Sam Barlow, where she portrays the dual role of Hannah and Eve Smith.[3] After previously working with Barlow on the cancelled game Legacy of Kain: Dead Sun,[4] he contacted her for the role after observing her work, stating that Seifert was "very good at picking up a line and intuitively pulling a lot of the subtext into her performance".[5] Seifert stated that the role was difficult to portray, commenting that shooting was "intense" and "rather exhausting".[6] Along with acting in the game, she also had a hand in the soundtrack, performing a song and helping alter the music.[6] Upon release, Her Story opened to instant and critical success, with critics praising the game as well as Seifert's performance; Justin Clark from GameSpot wrote that her performance "anchored" the game,[7] and Andy Keller of PC Gamer stated that her performance was "understated, realistic, and complex".[8] For the role, she won the Game Award for Best Performance in 2015.[9]

Seifert competed as a rhythmic gymnast at the 1990 Commonwealth Games and finished fourth in the individual competition, winning bronze medals in the hoop and ribbon disciplines.[2] She also participated in the 1992 Summer Olympics[10] finishing in 29th place in the individual rhythmic gymnastics competition.[11] She appeared on an episode of Would I Lie to You? as a guest of Gabby Logan due to their time competing against each other in gymnastics.
