Sega has just confirmed that the teaser site for the Vita game that said „the new story will begin?“ was for a new Samurai & Dragons game. This is the fifth season of Samurai & Dragons and they have released a new video of the game.
According to Siliconera:
„Samurai & Dragons, a free to play game designed in the vein of Kingdom Conquest, has been incredibly successful for Sega. The Vita game has tie-ups with other Vita games like Soul Sacrifice and Dead or Alive 5 Plus as well as a line up of console mascots. The new version, Intense Samurai & Dragons, kicks off on November 1. Sega localized the game in English, but so far has not released this version outside of Asia.“
