Dropzone

Dropzone is a shoot 'em up video game developed by Arena Graphics in 1984. It is a bi-directional, horizontally scrolling shoot 'em up in the style of Defender. It was designed and written by Archer MacLean, his first commercial video game. In fact, "Arena Graphics" is just a shell name for MacLean himself. It was released for the Atari 400/800, Commodore 64, Game Boy, Game Boy Color, Game Gear, Nintendo Entertainment System and Super Nintendo. Dropzone borrows many elements from the Defender, including the same font style, alien depictions and title screen depictions.

Story
On the surface of Jupiter's moon, Io, a scientific research base is under attack by aliens. The player dons a jetpack armed with a laser, a cloaking device and three smart bombs, to rescue the scientists and return them to the base.

Gameplay
The gameplay is much in the style of Defender, as well as Stargate, Scramble and even Robotron: 2084. Players control the hero trying to rescue the scientists on a horizontally side-scrolling game field. Players must elude or engage various aliens—some slow, others faster—and return the scientists to the base's eponymous dropzone. The aliens capture scientists walking along the ground. The player must shot the enemy aliens and catch the falling scientists. Sometimes the aliens will carry lethal androids instead, which must be avoided.

Development
MacLean purchased one of the first Atari 800's to be imported into the UK and started writing the game. It was then converted to the Commodore 64 (C64) by MacLean himself.

Of the C64 version of the game, MacLean said:

The name Dropzone was not settled on until shortly before the game went gold.
