Left 4 Dead:Extinction O-R

A brand new 5 comic story I am doing over my break. It takes place inbetween multiple scenarios from Left 4 Dead, where the four Survivors; Zoey,Bill,Francis,and loius, have to trudge through a museum and a forest. They discover a scientist's lost records, detailing a mutation in the viral infection. It can adapt to it's enviroment to infect and reanimate dead tissue cells. Unfortunately for them, the virus has reanimated a Spinosaurus.
