First, you have to beat every other level with Aragon (he has to make it to level 8) Then, you have to use the regain health cheat and the regain ammo cheat. You have to use the held in triangle attack. Once it comes to the point that Aragon has to protect Legolas, go up and help him. Then you have to go back down and protect the door. When they say the Archers are on the wall, go back up and kill the Archers. When all Archers are dead go back down to protect the door again. Last, when the Mountain Trolls come, use the held in triangle attack to kill them quickly and win the level. Also, when the Mountain Troll falls on the door, it doesn't mean that you have lost.</p>
