List of Super Smash Bros. for Nintendo 3DS / Wii U pre-release and unused content

This is a list of beta elements for the game Super Smash Bros. for Nintendo 3DS / Wii U.

Ice Climbers
According to Masahiro Sakurai on Famitsu, he was planning on adding the Ice Climbers for Super Smash Bros. for Nintendo 3DS / Wii U, but despite the characters running without problems on the Wii U version, the team had trouble getting the Ice Climbers working in the Nintendo 3DS version due to issues on the hardware power that Sakurai mentions in the Super Smash Bros. Direct video that all fighters will get 60 FPS in the Nintendo 3DS version during in the development that caused the problem during in the debug testing. However, remnants of their chant in the game can be found through a glitch.

Single-player story mode
Initially, Sakurai announced that the game would have a single-player story mode akin to Super Smash Bros. Brawl's Subspace Emissary. Later on, he revealed that this new mode would not have any cutscenes, due to Sakurai's dislike of people prematurely showing off the cutscenes on video-sharing sites such as YouTube and Twitch. Eventually however, the idea for a story mode of any kind was completely killed.

Trophies
Prior to the official Japan release of the game, a member of the ESRB leaked information about the game online, including unlockable characters and several trophies. The build for the game in these screenshots leaked online showed 686 trophies. The actual Japanese release for the game, however, features only 685 trophies. Analyzing the leak and the final version of the game, it was discovered the trophy for Tharja, a Fire Emblem character, was the trophy removed.

Mii Icons
In the E3 2014 trailer, during Multi-Man Mode the Mii icons were their faces. In the final version the icons are their weapon.
