So, how could would it be if there were death animations??

There could be atleast two variants for each occasion!:

Decapitation, death by fire, death by lava, death by hammer (maybe not), you name it! This would make the robots not die and become petrified the moment you hit them too much, but rather having a transition from animated to dead. (Naturally they would only play if there's an acceptable amount of robot parts not destroyed)

Just imagine the possibilities!
