8-Player Smash (8人乱闘, 8-Person Fray) is a gameplay mode in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate. This mode allows up to eight players to play together at once, as opposed to the standard four. In Ultimate, 8-Player Smash is not a separate mode with its own menu option; instead, Smash modes allow up to eight players to join.
In Super Smash Bros. for Wii U
8-Player Smash is a mode accessible within the Smash menu. It is similar to the regular Smash mode, but it allows up to eight players to join, instead of only four as in other modes. Coin Battles and Special Smash cannot be used in conjunction with 8-Player Smash. The 8-Player Smash mode can still be played with four or fewer players, in which case it functions largely identically to the regular Smash mode, with the exception of being able to do Coin Battles or Special Smash. With more than four players, many stages function differently, and some stages cannot be selected depending on the number of players.
In addition to red, blue, yellow, and green player colors for players 1-4 (red for player 1, blue for player 2, yellow for player 3, green for player 4), players 5-8 use the colors orange, cyan, purple, and slate, respectively. In Team Battles, an additional team color, the yellow team, can be selected, in addition to red, blue and green teams.
Only certain stages and their Ω forms can be selected; if there are more players present than a stage (or Ω form) allows, the stage's icon on the stage selection screen will be darkened and the stage will not be selectable. Additionally, several stages' hazards or other background elements will be disabled in 8-Player Smash. Custom stages are not available in 8-Player Smash, with the option on the stage select screen replaced with the button for DLC stages if any are installed, or another Ω form switch button otherwise.
In 8-Player Smash, Ω form stages will be scaled up to approximately 1.6 times their normal size. Battles with more than four players in other modes, such as All-Star Mode and horde battles in the Special Orders mode, will count as 8-Player Smash and thus use the 8-Player Smash versions of stages.
In Super Smash Bros. Ultimate
8-Player Smash is not a separate mode in Ultimate, and instead, all Smash modes (except for Custom Smash) allow up to eight players to join. Stages are not restricted by number of players, and only a few stages have differences by number of players.
Players 1-6 reuse their SSB4 colors (red for player 1, blue for player 2, yellow for player 3, green for player 4, orange for player 5, cyan for player 6), while players 7 and 8 have a switch of colors (pink for player 7 and violet for player 8). In Team Battles, the yellow team can be selected regardless of the number of players.
Pokémon Trainer functions differently in battles with more than four players. In such battles, the Pokémon Trainer will not be visible, but their voice can still be heard. The Poké Ball and its energy effects can be seen travelling to and from the foreground, implying that the Pokémon Trainer is in the foreground, outside of the camera's view.
Ditto cannot be summoned if there are 5 or more fighters.
Joker's taunts will not summon Morgana with 5 or more fighters.
All stages are available to play with any number of players. Custom stages are limited to four players once a part of the weight limit is reached.
In battles with more than four fighters (including Spirit battles with enough participants), Final Destination and all Ω form stages are scaled up to approximately 1.5 times their normal size. Additionally, a few stages have aesthetic differences in battles with more than four fighters (stage hazards and other elements that affect gameplay are retained with any number of players, as they can only be turned off in the Rules, with the sole exception of the Blowin' Up and Kitty Cover microgames being absent from WarioWare, Inc. in 8-Player). For Ω forms, only the main platform is scaled up, and the background is not moved to compensate, so on some stages, the platform will clip into elements of the background, or at least get much closer to them than usual.
