Some general information - this game is run using the GURPS system a very gritty and realistic system.
The general background is as follows:
4 years ago Norman Fletcher invented human immuno-nanobot colony (HINC) granting 99.9% of the population immunity from all viruses and bacterium, effectively curing all diseases. There are however those who were allergic to the nanobots and those went. Through life as normal as they could. Hospitals thinned down there services, people began to not care about immunisation, the cures for cancer etc as the nanobots covered it all. This was until a new airborne and infectious nanobot was developed to spread the nanos to the rest of the world it was this that seems to have causes something to go horribly wrong..
