March 17th, 2016. The official Digimon World -next 0rder- title site updated to reflect the game's launch, adding a page where tamers can enter their -next 0rder- product code to download a digital copy of the remastered Digimon World soundtrack. The total length of the OST is 110 minutes, comprising 36 tracks in all.
A separate section for those that bought the game's digital edition will open up on March 24th, 2016. Each person is limited to five downloads per product code, and the soundtrack will no longer be available after March 17th, 2016.
The DLC section of the site has also added a Hard Mode to the game. After downloading the day one patch, tamers can switch to Hard Mode by speaking to Punimon in Jijijmon's house, and they can also switch back at any time. The full effects of Hard Mode are unknown; the website only states that it increases the strength of the normal enemies the player encounters, and adjusts the game balance.
