The game takes place a year after the movie's ending. After defeating the Red Death, as a form of celebration, the Tribe has created a festival which they call "Thor'sday Thursday". On this festival, the Vikings always hold a dragon tournament and all of the teenagers are encouraged to participate with the dragons that they've trained. Players can play as either Astrid or Hiccup, the main human characters of the film. (Although Hiccup has his leg, he lost it in the film.) Before entering the actual tournament, players must use the training grounds to train their dragon to fight. After entering the tournament, they must defeat all of the other opponents and, eventually, win the dragon tournament (by defeating Snotlout Jorgenson) and be named dragon-taming champion. The player can create and customize their own dragon in the dragon den, where they also take care of the dragons, feeding it food the players have found all around Berk, the setting of the series.
After finishing dragon fights, players have to help Gobber gather ingredients for some food for the dragons. The ingredients are all located in the Wild Zone. To unlock the Wild Zone, the player must help a handyman Viking to repair the bridge connecting to the Wild Zone by navigating around Berk, borrowing tools from other Vikings. In the Wild Zone, the player can also enter caves and complete mini games with their dragon.[2]
The game also has online features.
