How to unlock the Killer Cure for a Pounding Headache achievement in Crackdown 3: Campaign - Definitive Guide
As you're ascending the tower there are a few spots where a group of 5 robots spawn for an easy ground pound or flying fist.
A lot easier then using cryo grenades or hoping they bunch up close enough
The Ground Pound Ability is unlocked once you reach Level 2 of the Strength Skill, though it is recommended that you're Skill Level 4+ for this to work.
This can be attempted at any stronghold Objective but it's every hard and rare that you get 5 enemies all bunched up. The best time to try this is when Elizabeth Niemand sends a Lockdown Retaliation on you (these happen naturally as you play through the game). Each time she sends one, more enemies spawn on top of you and the likelihood of them bunching up is higher.
The reason you want your Ground Pound at Level 4+ is because of the damage you deal and the moves area of effect. However it happens, simply jump up into the air and hold down . You can still move your Agent while doing this, so try get yourself in the best position so that you'll kill as many enemies as possible.
