How do you unlock the first bonus level on Slice It?

There are three bonus levels in LEGO Indiana Jones: (1) Ancient City, (2) Young Indy and (3) Warehouse. In order to unlock the bonus missions, you have to find the key. It's in Indy's office at Barlett College, but it is hidden in a very clever way. In order to find it, you will need several characters: (1) a scholar, (2) someone with explosives, (3) a short person, (4) someone with a shovel, (5) a high jumper, (6) and a Thuggee.


These six characters will help you access five chests hidden around the office. As you find each chest place it in the center of the office. The first chest is upstage right under glass. The second chest is way up high on a shelf in the back of the room. The third chest is behind the glyph panel upstage left. The fourth chest is under the shiny disks downstage left. The fifth chest is behind the Thuggee statue stage right.


Take the key to the artifact room. Find a blue diamond and place it on a pedestal, revealing the crank for the key. Turn the key and three slabs will open in the floor; however, in order to actually enter the bonus level you have to assemble all of the corresponding artifacts.


Ancient City will be unlocked after you complete any three artifacts.
Young Indy will be unlocked after you complete six more artifacts.
Warehouse will be unlocked after you complete nine more artifacts.


Remember artifacts are completed by finding all ten treasure chests in one level.
