Mob's book of Ideas

they're not zombies they're InFeCtEd

a deadly virus "escapes" from a research facility on the remote, densely populated, island. all communication has been cut. No ships or planes coming to help. the whole island has been forsaken to keep the breakout from the rest of the world. However there are survivors, the virus didn't actually hit a large portion of the population leaving them with no outside contact & dwindling supplies without even knowing it until containment efforts fail & the flood gates poor open.
