Helm's Deep-Breached Wall
On this level I found out the best charater to use is legolas when he has the purple arrows that kill the orcs with one or two shots. Ok when you start out run up close to the opening where the orcs are coming from as long as you're up there the gate wont take any damage. So when orcs come just shot them with a arrow or two. When you need anymore ammo and there is none lying around or if you just don't fill like going to get it. You can then press pause hold in L+R and while holding those two press A, down(on control pad), Y, up(on control pad). This will then make a sword sound which means you put int he right code. This code refills your ammo so you don't have to go looking for it.
So I hope this helps you out a lot.
