We already know that Hyrule Warriors won’t feature an online co-op mode like previous titles, but instead the Adventure Mode will feature some kind of online connectivity. Hyrule Warriors Producer Yosuke Hayashihas told Game Informer that “The Adventure Mode features a ‘Network Link’ feature. This allows you to add a ‘Link’ to your maps whose level is based on other users’ play data. If you come to this Link’s aid and fight alongside him, you’ll get access to special bonuses.”
