Masahiro Sakurai has commented on some of the similarities being shared in "Super Smash Bros 4" for Wii U and 3DS. According to a report from Game N Guide on July 23, the creator of the series revealed that the two versions are going to feature the same Boxing Ring and Wily Castle stages. However, there will be some minute differences. For example, the Wily Castle level may take place during daylight on the handheld system and at night on the home console.
Masahiro Sakurai reassured fans that both versions will generally contain a lot of different stages not found in the other. He confirmed in the past that "Super Smash Bros 4" for Wii U is going to feature more levels based on consoles video games. On the other hand, the ones found in "Super Smash Bros 4" for 3DS cater to other portable games.
Speaking of stages, the series creator also announced another stage for the home console iteration. Similar to the previous Sector Z and Corneria levels, players will be able to battle on top of The Great Fox spaceship, which originated from the Nintendo Gamecube video game, "Star Fox: Assault." The action title, which added new ground-based elements along with the trademarked space combat, was developed by Bandai Namco Games and published by Nintendo when it came out in 2005. A new entry into the "Star Fox" series was announced at E3 2014 with Shigeru Miyamoto working on the project.
Nintendo is collaborating with Bandai Namco Games again with the release of "Super Smash Bros 4" for Wii U and 3DS. The third-party company has been assisting Masahiro Sakurai and the rest of the staff at Sora with the development of both versions. The two releases are slated for later this year with the handheld product coming out on Oct. 2 while the console game has a holiday launch window.
