And it happens so fast, you might not catch it. As this is my own particular pet peeve affliction, my stupid brain Watches for it; expects it. Take a wave of small, very-fast-moving enemies. They’re zipping right along the maze you’ve set up and the first few enemies arrive at your expertly configured, tactically sound, death field kill zone…
