Game developer Marvelous began streaming two more gameplay videos on Sunday for its upcoming PlayStation Vita brawler action game Uppers.
The game will be set on an isolated island where brawling is the greatest form of entertainment.
The game was originally slated for release in Japan on April 21 for 6,980 yen (about US$60), but Marvelous announced that it would change the release date and price.
