Good combo:
If you are playing coop with 2 people have 1 be anti-tank and the other medic this way you have a good chance surviving most attacks

Capture the flag (tip):
When your ally has captured the flag fly very close to the carrier if he presses 'E' at the right time he can get into the plane and then just fly him back

Easy plane fly:
message: When you fly a plane you have to use the mouse to aim your flight if you change the controls from using the mouse to using the directional-arrows instead you fly alot easier

Hints:
message: Some funny things to do, is if you take a jeep, you can drive on people! It's kind of funny becaus they stay on the motor!

2. If you drive a plane, if you are over the water(land OK too), you can press Enter/exit vehicle button and you will fall down and scream: Shiranimo! Then you die, of course, you won't survive the fall from a higher place. Good luck!
