With Akuma being in both Street Fighter IV and Street Fighter V, Capcom UK has created a bit of a challenge for skilled practitioners of the Satsui no Hado. Through some careful arcade stick modding, it is possible to wire up your stick to play both games at the same time. As the Raging Demon input is the same across both games, you can essentially perform a double Raging Demon with careful timing.
Naming it the “Die 2000 Deaths!” challenge, Capcom UK tasked players like Tyrant, Shoryusengan, and even Yoshinori Ono himself to complete this devious task. You can check out their attempts in the video below — and if you think you can do better, make sure to leave a comment with your Double Demon attempt. If you’ve got the hardware, maybe set up Ultra Street Fighter II and Street Fighter III: 3rd Strike and see if you can pull off a Quadruple Demon!
