Bionicle Heroes

You can grind out the Lego pieces on the blue stage, start up the boss get enough Lego’s to get gold hero once press B to move the golden hero on the floor.

After the cut scene go to the right of the map, stand between two rocks there you are out of sight of the boss rubber band the A button so the bionicle continually attacks.

I used this spot with the unlocked boss character from beating the game facing the raised area. Depending on when you do this you’ll of course get the # o9f Lego pieces but it will also help with the kill achievements too.

ALSO: Spending the pieces for upgrades etc. does not effect this achievement the game tracks how many pieces you actually have even if you spent some.

The following video shows how to do this; I do not take credit for it.

For this achievement I would advise firstly upgrading all your bionicles to full strength then complete the main 'story'.

Follow the video example for about 20 minutes to get enough money to buy the canister locator.

After purchasing this go through the second playthrough collecting all the canisters. A few are difficult to work out how to get to so follow this guide http://www.gamefaqs.com/xbox360/935869-bionicle-heroes/faqs/... (created by stuartb0ffin).

Once you have finished collecting the gold medals for each level then go to the shop and see how many studs you have collected. Keep an eye on how close you are to the 5m point mark, bear in mind that you have spent studs along the way.

Purchase and complete the three bonus stages to get them to Gold as well, and afterwards return the blue stage guardian as shown in the helpful video above. For every 100,000 that you are short you will need to grind here for approximately 10 minutes although if you have been collecting absolutely everything you should already have this achievement. If not you won't be far short of getting it!

5,000,000 Lego Guide

Your level will be Decrepit Dungeon.

Towards the end of the level where the last Gold Piece is located. You will be placed in a room where enemies will spawn infinitely towards you down a blue water like hallway. They will continue to spawn until you fix the door trap. You can get almost 500k in less than 10 minutes doing this trick. Even better results using the boss character, and then just sit in a corner and hold down A. Can be done AFK as well, with turbo controller as well.

If you hit the part of the level where your going down a lava filled hallway you have gone too far.

Beforehand, Buying upgrades dosen't slow down this achievment. If you want fast money after the campaign buy secret level 1 and then keep replaying it. if you use the black grenade guy, you should get around 50-60k every time

Zaktan chamber is by Far faster for this achivement ,same method the location is wrong
