1UP reports that a second Vanquish demo will soon be dashing its way to consoles. The announcement was made by director Shinji Mikami and producer Atsushi Inaba during a stage show at TGS. The demo is set to offer a challenge mode, designed to provide a more challenging experience for skilled players. The new demo will arrive in Japan on September 22. We've contacted Sega to see if it will also see release outside of Japan.
