Note: This trick requires two controllers. Use the following trick to get all the vs. mode unlockables quickly.

At the level selection screen, press Y and the options should appear. Select "Sniper Showdown". Then where it reads "Point" change it to "Survivor". Next, set the number of lives to "1" and select "OK". Once back at the level selection screen, choose "Simple Map 1". You should start very close to your opponent. Shoot them and they should die in one hit. Once it is over, just select "Retry". Keep doing this until you unlock the desired bonus. When you unlock "Sure-Shot Scuffle Mode" at fifty matches, you can accumulate matches even faster because you can kill your opponent in one hit with any weapon.

Note: It is strongly recommended that you practice this a few times with a friend. Go to a level with pilots, Landmasters, and Arwings available. Try Corneria City, as there are many good places to board a ship. Choose a character that has a two to three star jumping ability. With a friend, make your way to either the Arwing or Landmaster. Have you or your friend jump onto the wing of the Arwing or the side of the Landmaster. Whoever does this should press R to keep steady. Then, have the other person press Z to start driving or flying.

Use the "Ride on Arwing?" hint. Some fun things to do include using hard-hitting weapons such as the homing rocket launcher, gatling gun, or machine gun. You can strap a Fireburst Pod onto the wing and have some nice explosive fun, watching the fireworks from the sky. Another good idea is to simply cover the tail of your ally's Arwing, just to make sure no one sneaks up behind you. Also, if you happen to have a Demon Launcher, you can really do some damage firing at other Arwings from a good spot. Overall, it would be a good idea to pack a Barrier along because you will be very vulnerable.
