Impend

300px Impend is a song included in the Halo 2 Original Soundtrack. It is heard on multiple occasions, the first time being during the final fight to deactivate the bomb on the level Cairo Station, it is enhanced by the loading of the MAC gun. It is also heard during the fight in which the Arbiter releases the prisoners on the level The Great Journey. It's only heard in Halo 2.

0:00 to 0:28 is almost exactly the same as the final part of Brothers In Arms. It then makes a transition to a low pitch percussion beat. From this point to the end, the track is mostly percussion, but it does include some vocals similar to that of the opening of the Halo Theme. The percussion has three levels. There is the soft, low, and gong-like beat that is slower than the actual beat of the song. There is a slightly higher beat that is a much sharper sound, and is the actual beat of the song. Then there the actual overlay of the song itself, and it is synchronized with the vocals. This allows the track to maintain intensity, but not be so slow as to go against the pace of the combat. You can listen to the song here. The length is 2 minutes and 21.897 seconds (2:21.897).
