Thank you @Roy_Wierer.Seda145
This is a great idea, i was already thinking about this. There is a great and almost perfect example in HotD Overkill (my favorite of this series).
You need to hit some attched targets on the attacking enemy to kill him. I did not try it till now but i like the idea to use something similar. Like jumping into the scene so you would have to know where this will happend to react fast enough to avoid this.
This is also a great idea, desctructible or at least responsible environments always look good and make a static world more living. I tested this with some static objects like lights and monitors. Feels like it is very performance heavy if you use it on to many objects.
But defenetly something to consider at a later point.
