The latest downloadable content for Zelda 2 includes an additional time attack stage and decreased pixel options.http://www.nintendoworldreport.com/newsArt.cfm?artid=17030Yesterday, Nintendo released new downloadable content packs for Zelda 2. Players have the option of downloading two new difficulty pixels and an extra stage.
Two of the new DLC packs, Hard Mode and Expert Mode, remove an extra pixel for gamers who can breeze through the regular difficulty setting. Both modes will adjust the length of Link's sword, making attacks more challenging.

Players who dare to tackle Expert Mode will find the difficulty increased threefold from the default setting. These modes do not support the Rankings or Challenges Modes.
The other new downloadable content pack is a Special Time Attack Stage. The stage includes a brand new level that ends with a fight against the new, undefeatable boss "Extortion Man." The Special Time Attack Stage is comparable in difficulty to the Ganon Castle stages. The stage supports online rankings.
Each of the new Zelda 2 DLC packs can be downloaded on WiiWare for 100 pieces of your soul.
