It has been announced that a very special animal of Link's is coming to Hyrule Warriors! That special animal is Epona! Eiji Aonuma announced on Miiverse that Epona will serve as a new "weapon" in the expansion.
Epona is being called a "weapon" because she can team up with Link to attack enemies. Aonuma described the gameplay experience by saying: "By riding Epona, I was able to blow herds of enemies away and gallop swiftly through the fields, and I had a lot of fun trying out this re-imagined version of her in Hyrule Warriors."
"In the Zelda series, players never had a chance to tackle bosses by galloping around them with Epona like in Hyrule Warriors," he said. "So I hope fans will enjoy playing as Zelda characters in a game with a different type of action than you typically find in the original series."
This expansion, The Master Quest Pack, will come out for Hyrule Warriors on October 16. This is included in the game's $20 DLC pass. Along with Epona, this expansion also adds a new scenario, adventure map, and pair of costumes. Later on there will be three more expansion packs. They are the Twilight Princess Pack, Majora's Mask Pack, and Boss Pack. With all of that, I recommend buying the DLC pass. Buying the pass also get you a free Dark Link costume.
