Dead Character Play
In the "Bionicle Heroes" game, it is possible to play as a dead character in specific instances. To start, you must die at the same time as a boss in one of the boss battles. If you die at the exact same time, your mask will show that you are dead and you will have no more hearts. Continue playing as appropriate. Although your character is dead, until the character is hit or changes to a new character, or the level changes, you can continue game play.
Extra Level Lego Pieces
To get the Lego pieces quickly and relatively easily, play in Hero mode and fight Roodaka. Press and hold the "A" button on the remote and the characters will auto-attack. Complete the level, and then go to the Matoran Enclave Shop. Upgrade Toa Nuparu and buy Bonus Level 1. Go to the Piraka Playground and walk to the other side. Look between the diving board and VIP Lounge. You should see a cave. Walk into the cave, and then take the leftmost portal. Select Toa Nuparu as the player, and fight and kill the enemies while collecting Lego pieces. You have a time limit, but you obtain as many pieces as you are able to collect in the time period.
Hiding Enemy
Start the level to fight Brutaka. Go to the elevator and notice the box. Take the two items off the box and put them on your character. Walk around to the front of the box and open it to find the hiding enemy. A Vahki is in the box. Kill the Vahki to obtain gold parts and a jailer mask.
Matoro Attack
When playing as Matoro, upgrade him as fully as possible. Wait until you see an enemy that is out of his normal range, and then zoom the camera to see the character. Shoot while the camera is zoomed. Matoro's attack will kill the enemy in a single shot, because in zoom the shot is stronger than average, even if the character is out of the normal range.
