In the year 2048, all technology will have changed, Including biological warfare. People are making Bioweapons to spread diseases across people, animals and plants.
One of the most powerful weapons that are being made are, properly invisible camouflage. Yes, I did say invisible camouflage, Called Quantum Stealth and made of MetaFlex. But my favorite would have to be, high-powered liquid laser beams, mostly for defensive uses only.
Another part of Biological Warfare is disease. One of the scariest diseases would have to Ebola. It could be genetically enhanced to not show symptoms for over 72 hours. Slowly killing you when you don’t even have a chance to stop it.
