When game first starts you are automatically flown home to a heli-pad

Armed with a heavy lifting helicopter your mission is to pick up blocks and
return them to your heli base.

Use the arrow buttons and gyro to fly your Blocklifter by aligning the blocks
below with the front of your Block-Lifter. Fly over a helipad to drop them
off. (maximum of 12 at a time)

Avoid the enemy, the turrets can be shot by your 3 other co-pilots or by aligning
them with your cross hair. Returning to a helipad restores the Blocklifters
health.

Collect fuel, during your flight or you will run out and crash and burn. Extra
lives may also be collected.
