To celebrate the birthday of Rin and Len on December 27th, SEGA will be releasing two new songs for Hatsune Miku: Project DIVA Arcade Future Tone, as well as 10 new modules. While the game is only playable in the arcades at the moment, it will be released on the PS4 as a digital download in Japan next year. The new songs and modules will be available starting December 22nd in Japan.
The new songs in question are Soundless Voice and Knife, both of which were already featured in Project Diva F 2nd. You can watch the video showing both songs here:
