We were shown a couple new DLC costumes, one for each of the main three cast members in the game. The new costumes resemble that of Kaine, young Nier, and older Nier’s (brother version only) clothes from the previous game.
▲ Clothes of an over-exposed woman (for 2B only)
▲ Clothes of a simple boy (for 9S only)
▲ Clothes of a man who destroyed the world (for A2 only)
These will be available (hopefully, if they finish making it on time! lol) on Tuesday, May 2nd for 1,500yen.
