After her voice performance in Assassin's Creed: Origins, Ubisoft asked her to audition for another project. After passing the first audition in London, Melissanthi flew back to Canada for the final audition. It was there she met with Alexios voice actor Michael Antonakos, with whom she performed the final audition with. She then started voice work in May 2017. Melissanthi's casting was then officially announced as the lead role in Assassin's Creed: Odyssey in June 2018. Ubisoft wished to hire as many native Greek speakers as possible.
After being cast Melissanthi researched female video game protagonists, but found the best way to embody Kassandra was to simply be herself. Playing Kassandra was also the first time Melissanthi performing a role in motion capture. To voice the character Melissanthi had to read a script in its entirety, taking anywhere from two to four hours. Regarding the romance in the game, Melissanthi thought it natural to be able to romance anyone. Melissanthi found the popular response to Kassandra initially overwhelming but filled her with joy. Melissanthi saves as many pieces fan-art of Kassandra as she can. As of January 2019, Melissanthi herself still hasn't played the game.
