What is the easiest way to spare Mettaton EX?
If you are like me, you made many mistakes during this fight and the other fights. Here is an easy way to spare Mettaton EX: • When the bombs start falling, shoot them so they can’t destroy the blocks. • When arms start falling, shoot the yellow blocks. If you shoot anywhere else, the arms will fall faster. • When the disco ball shows up, shoot it so the beams turn blue, then standstill. • This should allow you to spare him.
