Eragon Unlockables

It is said that powerful dragon riders protected once the lands of Alagaesia, but Galbatorix murdered them and claimed the throne. One day Eragon meets Brom who becomes his mentor, teaching him about magic, swordfighting and dragon riding. The 15 years old boy has visions of a charming elf woman, Arya, calling for his help so he sides with Brom in finding her. The lands have plenty of surprises in store for the two, as the evil king's forces are everywhere. In charge of the sinister army of Ra'zacs and Urgals is a powerful Shade named Durza. Ra'zacs resemble fleshy mummies with long sharp blades for hands, while Urgals are the sort of barbarians that you may have come across in other games.

Following the traces to save Arya, Eragon faces tons of enemies all through the south - western territories of Alagaesia. Brom and, later in game, Murthagh along with Saphira aid the young hero in his quest to defeat the Shade and free the beautiful elf woman. In addition to the main quest every level of the game contains a hidden secret dragon egg. Collecting these unlocks short movies on the making of the game available in the main menu and also promises a bonus stage (if you missed its location and got to a checkpoint better restart the mission as you can't go back anymore). Here's a list of what each egg will unlock.
