The Japanese PSN store has been graced with two new demos. GI Jockey 4 2007 and Heavenly Sword have both had playable nuggets placed online for download. For those of you still interested in Heavenly Sword but not ready to actually pay money for it, this new demo may be for you. Featuring Kai, instead of Nariko, the second demo allows you to play through one of her arrow shooting missions - also allowing you a taste of using aftertouch to guide her arrows.
As for GI Jockey, we're fairly certain that if you're not into horse racing then this demo won't change your mind. Keep your eye out for the Gran Turismo Prologue demo - due to drop on the Japanese PSN Store later today.
