Erebor: Belt
After Smaug is defeated, you will be in Erebor. After solving the block riddle, Bombur will want you to find a belt. Next to Thorin are wooden platforms. Climb them and get the belt. Then in the gear room, climb up the wooden platforms in the back of the room and put it in the gears.
Lake Town: Wine bottle riddle
Once you get all five of the wine bottle in Lake-Town, Malloc will tell you a riddle about how the bottles are arranged. The order is as follows:
1. Yellow Wine Bottle
2. Blue Wine Bottle
3. Red Wine Bottle
4. Black Wine Bottle
5. Purple Wine Bottle
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.
Mirkwood Forest: Avoiding spiders
Go to the North Camp. After you fill the hole with water, go to the camp. Slowly walk toward the gold chest until spiders appear. Then, run back to the water and jump onto the log. If done correctly, the spiders will have followed you to the water. The spiders will try to get you, but will instead fall in the water. You will not get the courage points, but you will have saved your life bubbles.
Stay at the North Camp. Destroy all the webs except the one that makes you fall into a pit. Forget that one and just continue with the game. When You return to the North Camp, destroy that web. You will fall into a pit. Normally a huge spider would have been in the pit, but if you killed all the spiders first, that spider will no longer appear.
Roast Mutton: Trolls
Do these followings in order to sneak by the Trolls and get the wallet. First, find the first Troll. He should be standing and doing nothing. Once he leaves, he will go to another area, then return to his original area. If he leaves his area, go and pass him by, then climb the small stairs. Once up, you will see a blue chest. The first Troll you once encountered will go to another area. Go to the area that the Troll has moved to. There about three Trolls here. You will see the troll rubbing his back against a tree trunk. Then, he will leave his area and rub his back against another tree trunk. When he is leaving his original area, and is going to another tree trunk, try not sneak when he leaves; you will not be very accurate and it will be very easy for the trolls to catch you. However, running works best. Run exactly when he leaves, and when he is not looking. Hide behind the rock that is near the Trolls' second area. Press [L] to kneel down so that the troll cannot see you. After that, you will see a trail. Go onto that trail. Keep in mind that there is another Troll, and he is sleeping. Stay on the trail only, not the leaves, or he will wake up. Press [L] to sneak past him. You will see two rocks. Jump on them until you see an obstacle course. Cross the obstacle course, and the second Troll you encountered will find two rocks and sit down to rest. In order to sneak by him, notice that when he yawns he is not paying attention to who is crossing his area. When he yawns, sneak by him, run to the rock, and press [L]. When you do, you will see the first Troll you encountered. He will walk back and fourth. When he is not looking, run to the rock and press [L]. Keep doing this maneuver to reach the wallet. Note: Try not to throw rocks at the trolls. If you do, he will start looking for you, and try to eat you.
The Unexpected Party: Finding the Waters Of Vigour
After you are done getting all the food for Bombur, go to a well in the apple orchard. The Hobbit that was standing there earlier should be gone. Press [B] and a bucket should come up with the Waters Of Vigour in it.
Water room puzzle
To gain entry to the water room, read the plaques on either side of the puzzle: "You must walk through EREBOR to reach it's heart". Approach the statue behind you and press [B]. The runes on the front spell EREBOR. Spell these out on the puzzle floor and the door will open. Note: Make sure to walk on the letters in the correct order.
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.
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.
In the last level (Gathering Of The Clouds), when you meet up with Lianna, you can get endless courage points by either waiting at the top of the ladder for Lianna to kill all of the Orcs, or by fighting them yourself. The Orcs will keep appearing, supplying you with endless courage points.
At the beginning of the final level (The Clouds Burst) after talking to Gandalf and receiving his message, look around. You will see three female Elves. Face away from Gandalf and Elvenking Thranduil. Then, go to the female elf on your left. Talk to this female elf seven times and a lot of courage points (value 50) will appear, which you will automatically collect. This will total 2,000 courage points. To talk seven times faster, press [Start]. If you do not receive the 2,000 courage points, you are probably talking to the wrong female elf. In this case, just try the others until you get the courage points.
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.
Mithrill Chainmail Vest
When you get to the level after defeating Smaug, one of the Dwarves should give you a chainmail vest.
Carrier upgrades
At the end of each level, you will be taken to the vendor. Here, you can buy upgrades for your rock bag and medicine chest. Each affects your carrying capacity. The upgrades are as follows:
Rock Bag
First upgrade: +10 rock carrying capacity; total of 20 rocks.
Second upgrade: +10 rock carrying capacity; total of 30 rocks.
Medicine Chest
First upgrade: +5 antidote and health potion carrying capacity; total of 10 each.
Second upgrade: +5 antidote and health potion carrying capacity; total of 15 each.
Walking stick
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.
Save regularly
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.
Glitch: Cut web with other objects
In the lair of the three spider sisters, before cutting some dwarves free, choose another item except for Sting. Bilbo will then cut the web with the walking stick, the stones and, if you put the ring on beforehand, his hands.
Glitch: Suicide
In a level with a deep chasm with a real bottom (Smaug's Lair recommended), jump down with the Stick or Sting at the ready. Wait one or two seconds (just enough time for Bilbo to reach the zone where he would die if he touched ground, but still a safe distance away from it), then, do a jump attack (press [B] ). Bilbo will instantly die, and float gently down towards the ground.
