TC Invaders is a 3D game of an anti-aircraft tank verses any number of hostile aliens in the sky.  You must align  your tank underneath the alien ship and shoot.  The alien ships also fire back when your tank is within their range.  The aliens will also descend closer to the ground.  The closer the aliens are, the easier it is for them to hit you.  A good strategy is to attack those aliens in groups while holding down the fire button.  Pass under the group while firing may shoot down several ships before they have the chance to hit you.
