Whenever we all play Super Smash Bros. our first goal is to unlock all the characters as fast as we can so we can beat the crap out of each other with our favorites. What I have here is a list of the easiest way to do this.
List of unlockable characters (in no particular order):
Mr. Game & Watch
In order to get all of these characters all you have to do is play 120 matches, unlocking a character every 10 completed matches. I was not able to verify if by playing all 120 matches will net you the characters in a specific order.
Now from my experience the most effective way to do this is:
Change the match type to Stock.
Set Stock to 1.
Choose a stage that is small with edges you can fall off easily. A great stage for this is Pupupu Land. In case the English name is different it’s the stage that looks like an old Gameboy screen and is an old Kirby level.
Jump off the stage and kill yourself.
Rinse and Repeat.
Honestly that is all there is to it. In this version of Super Smash Bros. obtaining all of the characters is rather simple than some crazy list of obstacles that we all have to go through to get to that last character. You should be able to complete this within about 30 min – 45 min. My matches were about 5 seconds each.
Beat Classic mode a second time.
Beat Classic Mode five times.
Beat Classic Mode ten times.
Beat Classic mode with Bowser on 6.0 difficulty or higher
Beat Classic Mode 4 times.
Beat Classic mode once.
Mr. Game & Watch
Beat Classic Mode with ten characters.
Beat Classic mode at 7.0 or higher or 25 times.
Beat Classic Mode with Marth on 2.0 difficulty or higher without using continues.
Beat Classic mode as Mario on 5.0 difficulty.
Beat Classic Mode with Link on level 5 difficulty.
Beat 100-Man Smash.
Best of luck!
