fuck my thinking emoji doesnt work

wait what about my story

oh right i forgot sorry

You hide behind some more cover and fire at the men yet again, and hit one of their guns.  The plasma bullets fizzle and sear the mans skin as he screams in agony as metal and blood evaporate giving the air an metallic smell.  Another is incapacitated from the molten metal on his skin, and the other drops to the floor.

You think you hear some metal scraping against something, and water rushing into a room.  You hear another shot and a glass window shattering, but you continue to fight.

The man on the ground fires a few more shots at the cover then suddenly stops.

What do you do?
A.  Peek out of cover and see what is wrong.
B.  Assume he is dead and move forward.
C.  Come out of cover and start firing in his general direction.
D.  Look around for that noise you heard.
E.  Other, explain.
