The king has entrusted you, a lowly page, with a dangerous mission: enter Baron Mortimer's castle in disguise and foil the baron's plot to seize the royal crown for himself!

In your quest for clues, you'll encounter the castle's inhabitants--from the servants who tend to the baron's every need to the alchemist who mixes strange potions in his quest for forbidden knowledge.

Using the Castle Guide map, you move from the dank, dark recesses of the dungeon to the high watchtowers where soldiers scan the horizon for enemies. You'll watch jousts and listen to troubadours. You'll gather tools and gold coins, search for hidden keyholes and doorways, and piece together a long-forgotten map to find a hidden escape tunnel. But beware! And think carefully before you answer any questions the castle characters ask you--while you spy on the baron, someone might be spying on you! Will you make your way back to the king's court--or spend the rest of your days in the dungeon?

Castle Explorer features the intricate detailed cross-sections of acclaimed artist Stephen Biesty with sweeping panoramas that you can scroll across in all directions, pinpointing people and places that interest you and clicking them for pop-up windows and hyperlinks that tell you all about them. Through the drawings you'll enter brilliantly rendered 3D rooms where you'll interact with the live-action characters and manipulate treasure chests, flasks, and more than 80 other 3D objects as you gather information in your search.
