Overview
In this guide I’ll show you one of the easiest ways to get this achievement!
First of all
You need to unlock Eli, coz he is the easiest character (due to his bombs) for getting this achievement. You can also do it with every other one if you have a few bombs.
Killing the shopkeeper
Just plant the first bomb next to him, and then plant the rest as he runs after you, it’s pretty easy.
