Street Fighter 6 has steadily added new fighters in the two years since its release, including many familiar faces. Now, a fighter who hasn’t been seen in 18 years will soon be introduced via DLC. C. Viper made her first and only appearance in Street Fighter 4 in 2008. Now she’s back to swing her fists in Street Fighter 6. The expansion is planned for fall 2025 and is part of the Year 3 Season Pass. You can also buy the undercover agent with coins in the shop.
