Has anyone been able to perform an object boost using the movable boxes located in several of the missions (Hankagai, Lost Cause, Drug Lab, etc)? Explanation here:
I know why this happens. It is because CZ DS has many animation sequences. And, the NPCs, in most cases, do not stop their sequences when their health reaches 0. This is obvious when you stand on the point where an NPC is trying to get to, shoot him with tons of bullets, and then move out of the way. He’ll get to his point, stop the animation, and then fall over dead. In the part of the video you linked to, that enemy had some sort of animation he was performing, and a death animation (you can see him fly back after he ‘dies’). I’d bet a million to one that those sequences are the culprit.
