Hey, so I just checked bungie.net and they've unvieled a new firefight map called rally point. Just thought I'de bring it to your attention, if you want to check it out here it is. It looks pretty similar to alpha site (or whatever it was called) hopefully it will play differently somehow.
Looks like a cool map, hopefully there are buildings you can go inside though. Reminds me a bit of that one halo 2 level outside of the building you go into when you have to kill the scarab.
It does, doesn't it? Choke point looks pretty cool. Hope they release one kinda like a bigger, better Longshore.
