We already knew that Link will be coming to Mario Kart 8 as part of its first DLC pack. However, Nintendo revealed that there will also be new tracks, including a Legend of Zeleda inspired track.
Included with the First DLC pack are three new characters (Link, Tanuki Mario, and Cat Peach) as well as new karts like the F-1 racer. This is 1 of 2 DLC packs coming for Mario Kart 8, with the second including Isabelle from Animal Crossing as a DLC racer.
The first DLC will launch next week for $7.99 of $11.99 if you buy the bundle version for the upcoming DLC Pack 2 (which will release at a later date).
