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 and Commodore 64, then later ported to the Nintendo Entertainment System, Game Boy, Game Gear and Game Boy Color. Dropzone borrows many elements from the arcade game Defender, including the same font style, alien depictions and title screen depictions.
