"I am obviously on the Anti-zombie bandwagon, because I am tired of zombies, they aren't that scary, I mean, we already have cannibals, AKA, intelligent zombies, so why not go for something like this:
A weaponized virus is created, but it is let loose in [Insert town name here]. The virus spreads in a gaseous form at first, but then it begins to infect through contact, and you can't tell who is infected. This leads to mass panic in the city, people wearing haz-mat suits, while people loot stores for supplies."

--to add to my Ebola-like virus. Dude that would be cool! also, people who can't afford hazmat suits kill each other (to kill off someof the uninfected) and make the government know about the cure. like, there IS a cure but the government is hiding it. One of the characters should be a doctor on the run because he stole the medicine or something like that.
