Killer Instinct

This can be done in Practice Mode.

The achievement description is misleading after the Season 3 update. Rather than cursing an opponent with Searing Skull, you specifically need to land an Instinct Curse, which is the shadow variant.

Spinal uses skulls as part of his special moves; activating Instinct Mode will give you the maximum amount of skulls and constantly regenerate them. Pause, hit or twice to get to Practice Options, set Instinct Meter to Infinite or Refill.

Activate Instinct Mode and facing right, use + with default controls, or any two punches. Once it hits, achievement unlocked.

Go to Local Play > Practice. Then choose Spinal as your main character, and any character as a dummy.

At the start of the match, press Start (menu button) and then press LB or RB twice to get to Practice options. Go down 4 options to Instinct Meter, and press right on the d-pad twice and it will be set to Infinite. You do this so that you can last in the mode forever, in case you mess up a few times.

Then just press RB and RT (heavy kick and punch) at the same time to activate Instinct Mode (might take a few tries if you are bad at the game like I am). Then just input quarter-circle forward and any punch (I chose to use the left stick for the quarter circle, but some PS3 / Tekken fans might like to use the D-pad). Quarter-circle forward is moving your left stick down, and then in a continuous motion sweeping it in a circular way to the right (or left if your character is on the left side) and then press X, Y, or RB (defaults for punch).

Might take a few tries to land it (if you suck at the game like I do). Once it lands though, you will get the achievement.


Here is a video below to demonstrate it in a simple way.
