Ermac's fatalities in 'Mortal Kombat X' are some of the most visually brutal in the game, and pulling them off requires precise timing. For his first fatality, 'Inner Workings,' you need to stand at mid-range, then input Down, Down, Back, Forward + Triangle (PS4) or Y (Xbox). The key is to make sure you're not too close or too far—just enough distance so Ermac doesn't accidentally whiff the move. I messed up a few times before getting it right, but when it lands, it’s satisfyingly gruesome—he rips out the opponent’s entrails and suspends them in mid-air before they collapse.
His second fatality, 'Pest Control,' is even more finicky. You have to be at sweep distance (just outside punch range) and input Back, Forward, Down, Back + Circle (PS4) or B (Xbox). The timing is tight, and if you rush it, the input won’t register. I recommend practicing in fatality training mode first. Once it connects, Ermac summons a swarm of insects that devour the opponent from the inside out. It’s disgusting in the best way possible—classic Mortal Kombat.
