Instructions
Play the "Indiana Jones" game on Wii from the beginning and complete the levels for "Raiders of the Lost Ark." The game sections are divided by movie so for best results, complete the levels in standard gameplay mode first.
Locate the parcel detector in level one of the "Temple of Doom" section. This parcel detector will help in "Free Play Mode." Continue playing the game through, if desired, or save and switch to "Free Play Mode." If you play the game through, after completing the levels for "The Last Crusade," save the game and restart from the main menu in "Free Play Mode."
Return to the "Raiders of the Lost Ark" section of the game and use the parcel detector in level six. You will find a parcel containing the treasure detector.
Switch the game to "Treasure Mode," in the main menu, and employ the treasure detector in each level to locate all of the artifacts or treasures.
