Chopper War Z 3D - Helicopter Adventures vs alien invader spaceship attack

Earth is under attack .
This is not a drill. The danger is imminent .
If we loose , our world as we know it will come to an end .

For years , We have been following the movement of those alien probes , without powerful telescopes .
We thought that if we keep quiet, they will continue in their path and leave our solar system.
Well, we were wrong ...

The first wave of spaceships destroyed our planet defense systems and all our satellites .
We were blind and deaf.
And the enemy fighter jets just kept on pounding and destroying our world.
When we thought that all is lost, One chopper brigade changed the course of the game, and gave us hope.
This is , Chopper war.

We are now ready to strike back.
Use the chopper brigade, and don't come back without a victory.
Mankind is counting on you .

Good luck soldier .
