Killing Machine

Killing Machine is a vertically scrolling shooter by Atlantis Software released in 1992. We're on a remote planet controlled by a giant brain that identifies you (and your sassy spaceship) as nothing less than an invading bacteria. Vermin, that needs to be wiped out!! The battlefield spans three levels and is stuffed full of kamikaze enemies - out for blood.

The first thing that struck me was the graphics which are uniquely colourful using a sweet palette. The smooth scrolling is slow and steady with impressive enemy sprites zipping across the screen. Sound effects go beyond mere bleeps for some rather raspy samples. Okay, they're not the greatest but the grunge works well and suits the styles.

Killing Machine is brutal and requires lots of practice before you get close to beating the first level. That learning curve is nothing less than painful. Keep at it - collecting the power-ups and learning the enemy attack patterns is a must. Or you die a suckers death. This isn't the best shooter, but it's good fun and I've enjoyed playing it. Highly recommended.
