According to IGN, Nintendo and Koei Tecmo have released the The Master Quest DLC Pack for Hyrule Warriors, and, from the looks of it, some pretty cool content is coming your way. This pack contains the use of Epona in battle while playing as Link, and a new Adventure Mode. This pack also includes five Legend Mode Scenarios, some new outfits for Cia and Lana and some new weapons, as well.
Nintendo has more information listed about the DLC packs at the Zelda website.
