[quote name='doubledown']Wow, I suck at this game....basically, everyone is like a level 16, and I am only at level 3. Thus, my gun selection appears to be different. Still learning though.
How do you call in helicopters and planes?[/QUOTE]
To get an airstrike you have to get 5 kills without dying, and to get a helicopter you have to get 7 kills.
Also, when you get 3 kills, you'll get a UAV which will show you the location of your enemies for 30 seconds. You activate all of these by pressing right on the d-pad.
