sorry about the double post, but in delta halo, when you came down in the drop pods at the beginning, if you use alot of rocket launcher ammo, go up to the second flood, then, go out of the broken barrier and there is a bush on the far right, run straight through it and you will find yourself on a ledge, jum up onto the ledge above you, then jump on the small ledge and onto the top storie, take an imidate (spelling) left and you will grab some rounds from the rocket launcher on the ground, this is also a great place to hide from the phantoms
Make way! Little Peaple First!
