*Watches closely*

Ideas (not sure whats possible):
Armor piercing rounds, explosive rounds, incinderary ammo, tracer rounds (emitts a little light material is a little hotter), IR goggles, parachute? Concision grenade, flashbang, smoke grenade, emp grenade, claymore/bouncing betty (immobil creature that explodes when enemies approach), sentry turret, uav (small flying creature with a high sight radius), assalt drone',emergency squad support (timed 1 use summon), gun attatchments (gun + item = modded gun (may take awhile to make all combinations)), riot shield, camo armor/guns for flavor and variety, gas mask. To balance more advanced stuff you could make them require more materials/next tier workshop. Again I don't know whats possible, just dumping random ideas. Can you set how long it takes to make something or make it require a certain skill level? I'll try to think of some civ stuff. If you get the electricity thing in there lamps, tv, radio, running water and so on. Mabey you could make a workshop Electric Generator as a custom workshop then make electric parts there and craft that stuff some where else at least untill you make up a better way (did I explain that right?)
P.S. Typing on a phone is annoying and sorry for the wall of text.
