Co-op mode is a mode in Super Smash Bros. Brawl, Super Smash Bros. 4, and Super Smash Bros. Ultimate where the player can get another player to help them with most 1 player modes, over Wifi or directly.
Over an Internet Connection[]
Over the Internet, a player can get others to help with the Home-run Contest game mode and the Multi-Man Brawl game mode.
In Super Smash Bros. Brawl[]
In Brawl, a player can get a friend to help them (with 1 player modes --such as The Subspace Emissary, All-Star Mode, Boss Battles, Target Test, Home-run Contest, or Multi-Man Brawl).
Subspace Emissary[]
The character allowance stays the same, but first player gets three characters (5 in the Great Maze) and the other gets one, rather than 1 player getting all of them. This can make things easier or harder depending on the stage the players are on. If they are on a stage that has lots of enemies, this can help because there are twice the amount of people helping to defeat the enemies and one more person that they have to gang up on. But on other stages, such as stages with a boss, this can be a burden. For example, if Tabuu uses his Off Waves attack, both the players may be KO'd, thus losing the players 2 characters rather than just one. Note that player 2 can join at anytime by pressing the start or + button. Also, if Player 2 is KO'd and no other characters remain, Player 1 can still be alive and continue on their own until they complete the stage or are KO'd. However, if Player 1 is KO'd and no other characters remain, both players are sent to the SSE's Continue screen.
All Star Mode[]
If two players attempt to do All Star Mode, they will go though the normal format with a few minor changes such as:
- The final foe-Olimar now has a second Olimar to help him out.
- Both players must remain alive. If one player is KO'd, the other player cannot still be alive and continue on their own. Both players are sent to the Continue screen. It is as if both players have been defeated.
- Instead of having three Heart Containers, there are six (with the two extras being below the platforms that hold the normal three).
- At the end of the event, you get a combine two-player score instead of the two scores being recorded onto both the characters, although you receive both the trophies. However, the Final Smash trophies are not unlocked for the normal Trophy collection. Both the Final Smash trophies and high scores (for co-op) are tracked into a unique reserved slot. This also does not unlock the Challenges. The only way to unlock them (along with the Final Smash trophies) is by doing All Star on solo. (That is, such as doing All Star with any character and on any difficulty or doing it with 10 different characters.)
Boss Battles[]
Like All Star, Boss Battles has a very similar format to 1 player Boss Battles but has a few slight differences such as:
- Like All Star, both players must remain alive. If either player is KO'd, the other may not carry on by his or herself.
- Also like All Star, there are more Heart Containers (six instead of three)
- Again like All Star, there is only one final score rather than two to be recorded onto the character. Challenges cannot be unlocked through co-op play, only in solo mode. (That is, such as doing Boss Battles with any character and on any difficulty or doing it with 10 different characters.)
Target Test, Multi Man Brawl, and Home-Run Contest[]
- Target Test and Multi Man Brawl are pretty much the same format, only there are two people playing rather than one.
- Home-Run Contest can be played either with both players combined or one player after the other.
