Thanks to the game's sophisticated physics and damage modeling, the results of your attacks will often prove surprising no matter how accurate you think you are. Since maps tend to be strewn with explosives, and the worms themselves explode when they die, oftentimes the results of a successful strike are anything but predictable as an incredible chain reaction ensues. This tightly controlled chaos, together with the precise targeting system and plausible physics, is also essential to this game's success. And the automatic instant replay on especially unbelievable chains of events is a nice touch.
