Defender was widely acknowledged by many as an instant classic upon its release into the arcade. Fans of the game held their breath in baited anticipation as they waited for the first home versions to appear in the shops. Surely the bespoke controls of Defender parent could never be replicated on the humble Competition Pro Joystick. Could it?
Archer Maclean released Dropzone on the C64 in 1985 (Initial development of the game took place on an Atari 800 that reportedly ran 2 ½ times faster than its C64 counterpart) - a tight, challenging and finely balanced shooter that perfectly exemplified how a complex game could be controlled by a stick and a single button.
All aspects of the Defender game mechanics are unashamedly present including the hovering alien types awaiting their fate, the end-of-wave re-spawning enemy should the player dawdle too long and even the cloak from Stargate makes an appearance for good measure.
