 On May 11, 2010, Square Enix released a piece of downloadable content for the game, titled "The World of Recycled Vessel". The small expansion features a series of fifteen battles with the incarnation of Nier other than the one in the specific version of the game. Nier enters the battles in a dream world accessed through a diary in his house. The expansion offers new costumes and weapons for the game. Square Enix executive producer Yosuke Saito later commented that "a number of things" related to Nier were in progress, and that an announcement could be due in 2011. The only announcement ended up not being for a new Nier video game, but instead for a live evening concert for Nier's music titled "Nier Night ~ Evening of Madness" which took place on October 28, 2011.
