Below you'll find the easiest method to get each achievement. Alternatively, if you don't own the Premium Pack or don't know anyone who does, you'll have to do most of these in Battle 64.

Unfortunately, some of these are unobtainable if you don't own the premium pack, so your best bet would be to find a boosting partner that does own it and is willing to host a few matches for you.

Also, at the bottom you'll find a step-by-step roadmap.

• Bomber ONE
  Come 1st in a Battle 64
  Start up a Battle 64 private match with a friend and win. Simple enough.

• Area hog
  Dominate an area in a Battle 64
  You'll need 5 or more friends for this. Start up a private Battle 64 and have everyone blow themselves up so you're the only one in your zone OR try your luck at the regular Battle 64 mode.

• Grand Prix Winner
  Win a Grand Prix
  Pretty self explanatory. Start up a private Grand Prix match and win.

• PERFECT
  Get a PERFECT in a Grand Prix
  Start up a private Grand Prix match and set it to Crystals. Get all the crystals and this achievement is yours.

• Safety first
  Finish a round in a Grand Prix without dying
  Easy. Using the same settings as the Perfect achievement, grab all the crystals without your friend killing you and you'll get this.

• Standard winner
  Win a Standard Game
  Start up a Standard private match and have your friend blow himself up upon starting. Quick and easy.

• A reliable partner
  Win a game while riding Louie
  I put this one here but you can totally do it in Grand Prix as well. Start up a private Standard or Grand Prix match, get a Louie and win.

• It’ll do, I guess
  Win a game without picking up a single item panel
  I prefer to do this in Standard. Start up a private Standard Match and immediately have your friend blow themselves up.

• Self-destruction
  Died by your own bomb
  You'll naturally get this if you're boosting with a friend. Simply choose any mode and blow yourself up.

• Blocks from above
  Died by destroying a Block
  This is pretty easy to get in regular Battle 64 but if you're boosting with a friend, you can set up a Standard Match with a 1 minute timer. As soon as you start, blocks will begin falling. Just wait until you get crushed and this is yours.

• Trip into the abyss
  Get pushed into the Abyss
  You'll need a friend who has either Simon or Raiden. Select Central Yard or Pixel Land in a Standard private match. Line yourself up with a hole and have your friend use their character's ability on you.

• 8 Bomberman Bros*
  Win a battle with all 8 Brothers
  For this one you'll need a boosting partner. You'll need to win 8 matches against your friend, and for every match you have to play as a different Bomberman sibling.

*For 8 Bomberman Bros, I created a discussion HERE.
If it becomes active enough, it might serve as a place to find boosting partners.

Make sure that for all of these you're choosing a different Bomberman color.

5. Start a Standard Match, here you'll get:

'Area Hog' is the only achievement that's harder to obtain in private matches as it requires a minimum of five players, however, you can get this in regular Battle 64; either defeat everyone during a battle phase OR during the movement phase walk around the various maps until you find an empty one.
