The last two DLC fighters for Super Smash Bros. for 3DS/Wii U, Corrin and Bayonetta, are now available. At long last, the development on Smash for has ended!! To all of the staff who were involved in this project, thank you for all your hard work. To all who supported and followed the game and its development, thank you so very much. Personally, I’m happy I can finally take an extended vacation.
The fighters themselves become the sources of new excitement. That’s why the new fighters can do things the others cannot, to bring to life a number of battles that did not previously exist. Smash is much more extravagant in its design than other fighting games, development is difficult, and I have to deal with oversight from the original creators, but I have to do my best.
