If the only way to down a helicopter is to get it to fly "through" an road sign and then there is a huge obstacle right in front of said road sign that pretty much destroys your car, even with full upgrades, does not help the game get any more fun.
Difficulty curve is WAY too high. Upgrades don't seem to do very much. And I can't stand when a game has it's main controls are WASD then you go to the menu and you got to pick up the mouse every 30-45 seconds.
