Stage 4 (Roast Mutton): The battle with the Trolls | Walkthrough LEGO The Hobbit Guide

In the camp, there are many destructible objects

You can start the battle with the trolls, as any of the dwarves. Use the opportunity to destroy the objects in the camp, thanks to which you will obtain studs and supplies. while doing that, stay away from the closest of the trolls, as well as from the other ones, which the allies jumped.

Turn to the right side of the camp. You need to hold down the indicated key/button here and build a catapult. Once the catapult is ready, switch to Kili and select Kili's Bow. Aim at the catapult's target (the above screenshot), and stat the entire structure running. If you have done everything correctly, the first one of the trolls will be stunned.

Approach the dwarf and Buddy-Up with him.

Approach one of the dwarves, who should be standing next to the stunned troll, and press the Buddy-Up key/button. After your character jumps onto the ally, he should land an automatic attack and eliminate the first troll.

Note - If you are playing with a human player, you will most probably have to approach the stunned troll, before you land the attack.

Press the keys that appear on the screen

Right after the first troll is defeated, a cutscene of the tussle with the other troll. In this case, the key to success is pressing the keys indicated by the game, rhythmically (they will change, occasionally!). The second troll will soon be incapacitated.

Eliminate the second troll, thanks to teamwork

Just like in the case of the first troll, you need to switch to any of the dwarves, approach the ally standing next to the stunned monster and press the Buddy-Up key/button. There is still one more to eliminate.

Be careful here, because the last troll will start throwing heavy objects at the protagonists. Avoid them and additionally, switch to Kili. Prepare Kili's Bow and aim it at the nest shown in the above screenshot. However, shoot only when the troll walks directly under the nest, thanks to which he will be stunned. You can now approach the monster and, in the way that you have already learned, Buddy-Up. Unfortunately, defeating all of the trolls does not end this stage.
