Damaging the forms of robots (citizens or shepherds alike) will decrease their health. From there, you can actually reach a hazard point where if you give them a few more seconds, the body will explode. By this idea alone, every body you headland on is a walking bomb! Use this to your advantage to take out several groups of enemies, should you come across a lengthy group.
I acquired this during the run through the Starcophagus, actually. However, should it not present itself to you until that time, I would instead suggest one better location. In the Grid Clash arena you will come across several groupings of Pawns and Bishops while trying to upload Rook Data. You can use your Rook's attack ability which is
to behead or break several robots, and as there are some nodes that will spawn more, they may walk right into the path of the explosions.
I'm not sure if this is actually given for the explosion of your former body if you take off before it explodes.
