Super Smash Bros. Strife

Super Smash Bros. Strife would be the 5th installment in the Smash Bros. series, available for the Nintendo Switch. Strife's gameplay and features would follow those of its predecessor: Super Smash Bros. for 3DS and Wii U.

Characters
Super Smash Bros. Strife features an even larger cast of characters than before.

In Smash 4, the concept of having alternate "skins" of characters that had the exact same moveset as other characters but given their own names and voices was first implemented in the series with characters such as Bowser Jr. and the Koopalings and Olimar and Alph. In Strife, this concept would be explored further, going so far as to have an alternate (sometimes unlockable) skin for almost every character.

Characters in bold must be unlocked.
