Dropzone

Dropzone is basically a Defender variant, closely recreating the gameplay
of the original Defender with its speedy scrolling and frantic gameplay.

The player controls a spaceman with a jet-pack, flying across a barren
landscape whose skies are inhabited by a number of different aliens, from the
simple Planter to the slowly advancing Blunder Storm or the quick, aggressive
Nemesite.

Planters and Nemesites will try to pickup the small men walking on the
surface, who must then be rescued. The player has to shoot down the alien,
while avoiding to hit the man. Sometimes, the aliens will carry an android,
which is similar to the human but deadly. Care must be taken so as to not pick
up the androids. All men must be transported to a surface base, where they are
put in safety – this is the Dropzone.
