Features He knows he is the best, and no one stands a chance. All he needs in order to sweep every trainer, gym leader and organized crime syndicate in Kanto. He starts his travels with a Magikarp and a Master Ball. He has a plan, and he is going to follow through. Clay has one mission on his mind, to contour and beat every gym leader like no one has ever beaten them before. In this first ever open-world expansion of Kanto you play as Clay an overly cocky and thorough Pokemon trainer. However, since Clays Calamity II has been growing in popularity, many people are requested the first game be released. Created in early 2016, this patch was never meant to be released to the public as it was a custom mod for a friend. This was the very first open world Pokemon game.
