How to unlock the Headache relief achievement in Zombie Army Trilogy - Definitive Guide
Start on The Keep - Episode Three on cadet difficulty and default enemy spawns.
Play until you reach the bridge that is rigged with explosives and the tower with the skeleton chained to the window. Progress a little further until you get a checkpoint.
At this point, there will be (in my experience) three zombie snipers and five summoners. Once you have killed four summoners, RESTART CHECKPOINT. As soon as you kill the fifth, you will get a checkpoint that will make you start over.
Watch the video to learn where they spawn so you do not have to deal with other enemies. Aim for their upper chest, so you can get a headshot very easily.
Load up

(0:24 !) at this time mark you see the place, it's right after the safe house.
Run out and kill the summoner, reload checkpoint.... kill him....etc...
Summoners float off the ground and summon zombies near you, they only take one headshot to kill. A good place to farm this is Episode 2 Mission 4: Terminal because there is one at the beginning. Once you have killed him, restart the last checkpoint. Your progress will not be lost. Do this 25 times and the trophy is yours.
Summoners are somewhat rare. They must suffer a head shot to die and summon zombie waves but don't actually attack you themselves. Just scope in when they say 'RIIIIISE' as this is the best time to score a head shot as the head doesn't move as much. A good farm spot is in Episode 2, Chapter 3: 'Crucible of Evil'. After leaving the mannequin shop, you'll come outside to a burning plane you will get a checkpoint here. Go down the right alley and four summoners will jump on the side pillars, so kill them and reload the checkpoint.
You can also kill fire demons there!
