Gearheads of War

Well, i'm still waiting on my brand new 360 to come from microsoft. Should take couple more days till i receive it. So i haven't gotten the chance to download annxex nor even play it yet. So I have questions about the new game-mode.

1. Once you are shot down, can you revive yourself just like Execution?

2. When you shoot someone down, you can just kill them off far range just like Warzone?  

3. Everytime the circle spawns, is it always random?

4. Do the circle always spawns on the unique weapon in the map?

5. There are three HUDS in Annex, two of them is the current score for the COG and Locust team, the other HUD is where the circle is spawned at which shows a picture of a weapon, correct?

6. Anything else I need to know about Annex or anything I didn't mention explained please.

Finally, what do you guys think about Annex, is it your favorite gamemode or is it the worst?
