At first glance, Spectro Destroyer could be one of any number of platform shooters. Run and gun through the levels, taking out alien scum and robotic sentries trying to halt your progress. Then you realize there's more to this than shooting everything in sight. It's more like line-of-sight. In fact, Spectro Destroyer is just the opposite of the "shoot first, ask questions later" side-scrollers like Metal Slug and Abuse. Instead, it's an amalgam of a platform shooter and a physics puzzle. And that, my friends, is a lot of fun.

Dynamic Systems, created by Lorenzo Nuvoletta, is another in a long line of games first made popular by The Incredible Machine, where you must fabricate an overly elaborate system of simple machines to perform a task that would hardly impress a toddler: putting a ball in a bucket.
