When you can play levels over again, use this trick. It will take several attempts, depending on your skill. In all of the levels (excluding Weathertop, Amon Hen, Plains of Rohan, Breached Wall, and the Helms Deep), you can complete the level with an "Excellent" rank, just by killing one or two Orcs, and getting "Excellent". Kill a few Orcs at the beginning of the level (five or more), getting an "Excellent" rank. Then, run near to the end of the level. For example, in the Gates of Moria level kill off the first few Orcs with your Linked Move until the intermission sequence with the arrow and the Orc and Gimli. Then, run to the part where you need to kill the Watcher, and do not kill any Orcs on the way, unless you have to. No orcs will follow you to the Boss part after you have started it. Kill the Watcher. When your kills get counted, as you will see, you will have more "Excellent" kills.
