Sony Japan have announced that PSN title The Last Guy (314mb) will be available in Japan on July 31, for 500 yen. Below is also a gameplay video of The Last Guy, courtesy of killingthee via YouTube.
To quote: In The Last Guy Japan Premium, you play as Last Guy, who's come from the Himalayas to save the people of Asakusa, one of Tokyo's hot tourist spots, from attacking zombies. Your job is simple: find people remaining in the Asakusa area and lead them to special escape zones.
As suggested in the original teaser trailer from two weeks back, the game makes use of real life aerial photos of the Asakusa area. Judging by the few screenshots Sony handed out today and the new trailer video that was posted at the game's official site, gameplay appears to be viewed from a strictly overhead perspective.
