This is a Halo: Reach Beta/Halo 3 community put together by Krayte entitled, "This Bitter Earth". The Reach gameplay is obviously not that great since it all came from the Beta, but it's good considering that fact, and the Halo 3 gameplay is solid as well. The editing is what makes the video though; the intro is very creative and there a lot of incredibly well-done angles (3:24 is pretty awesome) and effects (I thought that the spinning Earth at 2:10 was really cool). The soundtrack is wonderful, and the editing flows with it very well. The only problem I have with this video is that the angles got excessive at times. Anyways, enjoy!
