Set the game to two players and let the other person get three goals then come back on him to win the trophy. You could also boost it with a buddy online.

Win a duel with every geon. Can also be accomplished with 2 players.

Go through all the ranks up to division 1 and win one game in division 1 to attain this trophy. I highly recommend using the Greed Geon for his sucking powers or the Shock Geon. Although a bit slower, he is able to lay down a trail of electricity on top of the goal to prevent the opponent from scoring.

Do this with a buddy online or use two controllers and do it yourself.

Get online and play!

Same as usual, set to 2 players and do not hit the geon powerball attack button during the whole match and win. You can use your jump attack though.

You have to win one of each of these: league, duel, time trial, mini-game, last man standing and team duel. Due to the weak online participation, the last man standing and team duel can be accomplished with 4 controllers or using the XMB menu to switch the controller number in the accessories menu of the XMB. After each switch select a geon and play.

Get Golds on all the time trial levels. Probably the hardest of the bunch. Spam the heck out of the Greed Geon; he is your friend.

Not as easy as it sounds since this is the hardest division to win. Spam the Greed or Shock Geon. You can quit the game if you are losing and still get the trophy as well.

Boost Boost Boost. The online is for this game is D-E-A-D. Good luck getting this the intended way.

You do not have to get medals for these. Just complete them.

This will more than likely unlock when you are boosting "Gimme gimme world domination." All modes contribute to this number. You can find your points in the trophy menu in the Geon game.
