Nintendo has announced Version 1.0.4 for Super Smash Bros on 3DS, which will tweak the game's balance.
According to a post on Nintendo's website, the update promises to "adjust the game balance" and "fix some of the problems." It also warns that if you download the patch, which is required for online play, you'll be unable to play offline multiplayer with users who stick with Version 1.0.3.
Replay data saved in 1.0.3. cannot be played back once Smash receives the new update, so commit those awesome moments to memory. The patch is scheduled for delivery this November.
