Saw M is an exhilarating casual game. It will not be exaggerating to say that human history is somehow a history full of suppression, vividly demonstrating the principle of survival of the fittest. In this game, similar rules apply. Ruthlessness is the key to survival. Initially serving as a tool with a long blade with sharp points or teeth along with one of its edges, a saw will turn into a deadly weapon. The velocity of the vehicle carrying the saw will enhance its lethality to an unimaginable extent!
