In Lake-Town you have to put five bottles in order in the Cider House cellar. This is the order from left to right: Yellow, Blue, Red, Black, and Purple.
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.
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.
Easy courage points
On the last level when you meet Liana, she will start fighting the Goblins. There will be an unlimited amount of them. If you need to level up, stay there for awhile and collect all of the courage points.
Water Room Codes
When entering the Water Room in the level, 'Gathering of the Clouds', you have to walk through the code 'EREBOR' (shown under his statue) to enter the room. If you put in the coded names 'DURIN', 'THORIN', 'THRAIN', and 'THROR', it opens up passages to locked treasure chests.
Until you obtain Sting, the walking stick will be used mainly for combat. Once you do obtain Sting, drop the combat aspect and only use it for jumping. When moving forward, quickly press L then A to use your walking stick to jump. Be careful, using it on shorter jumps may result in over-jumping.
It is very easy to die quickly in this game, whether it is from accidentally falling off a ledge, a severe poisoning, or being caught sneaking around. Save regularly to prevent jumping back a quest or more.
