This week’s issue of Weekly Famitsu contained an interview with the dev team behind Splatoon, and Nintendo Everything translated the pages. They mentioned a few interesting facts (there’s a map of Inkopolis, but only they own it and it’s just a sketch guideline). Two new stages, called Piranha Pit and Ancho-V Games (at least in Japan) will have very narrow corridors and require some unique strategies. Also? There will be no more updates to the game after January 2016, so we’ll have seen all the stages and weapons by February — the final total will be 14 stages.
When pressed for an answer as to why the updates would stop, the team said “right now there are already 14 stages and over 70 kinds of weapons. So if [we] add even more, it would be hard for players to memorize all of them, especially when considering weapon compatibility with stages.” Pffffft, I’m sure. It’s more likely that something else is about to take all their attention away. It has also been announced that the final Super Smash Bros. update would occur in February. I would not be surprised if major news about the NX comes out shortly after that.
Don’t worry about the kind of updates that tweak and balance online play to avoid exploits. The team says those will continue. They closed by saying, “We can really feel the reaction from Japanese users to a degree, but recently we can also feel that people from outside Japan are also accepting this, so we’re really glad.”
