EMP granade seems overpowered. It’s very easy to make, consumes only non strategic, ubiquitous resources. You can craft dozens of them in no time. Its construction demands some electronics skill, which is easily accessible. Virtually every house has some electric stuff, that can be dissasambled for experience.
One EMP granade destroys a turret with ease. Its explosion can’t affect you. If a bunch of manhacks molests you, you can simply drop one under your feet to get rid of them.
My idea. Add some energetic substrate to the recipe. Atleast some batteries, maybe even plutonium cells. This would make them a more strategic weapon. Currently, EMP granade is no brainer. When i see a robotic opponent i simply start throwing them at en masse.
