OK, so maybe murder was never quite on the table, but the Phanatic should still be considered a dangerous maniac to be avoided at all costs. Those air cannons pack a heavy punch, and the poor pig-man got lit up from close range. That shit hurts!
We don't know what happened to pig-man after this attempt on his life was made. It is very likely that he suffered massive internal injuries and had to be euthanized.
