It won't really be an action packed RP since the only real threats are Mixi, the enviroment, and other people.
There's also two other groups. Bikers/Gangers are exactly what they sound like, the big tough bullies. They also do mercenary work. The Tested are a cult that think Mixi is some sort of divine wrath, and they also have the only real cure for Mixi. It helps since they purposely infect themselves with it.
Mixi is really nasty, by the way.
