Paratroopers

Playing Instructions
It gets awfully lonely sitting on your own in a bunker, with only a cold greasy
ack ack gun to converse with whilst waiting for the enemy to drop in. But be
warned, this ain't no social visit.
Your task is to prevent the invading forces from landing. You must shoot the
helicopters and paratroopers as they descend. But be careful, don't get trigger
happy, that ammunition is scarce and you lose points every time you fire. So
don't end up with a negative score.
You lose the game if your bunker is hit by descending paratroopers and if you
allow five paratroopers to land and man the tank which will drive out and blow
you into oblivion.

Use cursor keys and 'A' to fire
or
Define your own movement and fire keys.
or
Use a protek joystick.
