The Hobbit Cheats

Mirkwood Forest: Fighting spiders
When fighting the spiders, stay up on one of the rocks. Throw rocks at her minions. If you run out of rocks, just slpp on your ring and sneak (or she will hear you and attack), over to some rocks and get them. Hint: Defeating Smaug: Stay behind the debris until all of the fire is gone. Even though he stops, some fire is still there and it will kill even if you take one step out. The ring will not help you at all.

Saving Beorn
In order to save Beorn on the last level, you must push four different blue barrels located around the area. Follow the courage crystals and do not stop to fight. Use the ring when you encounter enemies, because you are timed.

Obtaining equipment
There are three items you can acquire throughout the game: the walking stick, throwing rocks, and Sting. The walking stick can be found in a chest in Bag End at the Shire (first level). The rocks can be found in a grove of apple trees in the Shire. Sting is obtained in the troll cave at the end of that level.
