Hoverbike Vs Chopper War

The military are not taking any chances and will stop at nothing until all the Hoverbikes have all been destroyed. For some reason, you've been dragged through a time portal and arrived on planet Earth.

All you and your Hoverbikes team want to do, is return home, but you must avoid the hostile choppers as they think you are here to invade. Do what you can to survive, shoot those helicopters down if you have to, but make no mistake, you will be surrounded and wiped off the planet if you do not keep your pilot skills razor sharp.

Good luck piloting 6 of the most advanced Hoverbikes.
Sharp shooting and lightning agility will win the battle.
This is war, this is Hoverbike Vs Chopper Wars.
