BCM545 - Rejoined landing battle, set-up tips and battling to music

Halo, level 4 ('The Silent Cartographer') on Heroic. Partly in light of further probing, I wanted to add some tips or suggestions in regard to set-up work. I do that in the first two minutes here, while creating a set-up in which battle music has been triggered, with the intention of arriving from the normal direction. The rest of the movie comprises four glorious battles using that set-up, and I must say, the music really adds something. For full details and written commentary see my site.
