it seems that window is made of Bulletproof glass.
steel pillars are also not penetrable with our gun
But your bullet can pierce through concrete easily.
consider shooting while robot is behind brick walls
We remember how You successfully conquered upto map last time ;
we are really happy to have our hero back .
grab your sniper and let's head to Map
Robot Has Been destroyed successfully
Humanity will remember your contribution
At that moment, Robot was not there where you shot
That Robot escaped the zone unaltered.
