This game will come out soon. Here's the plot.

A while before Perez killed the bat that started the virus, the bat had a kid, and now you have to make sure that you find that bat, kill it, and kill the person who ate the child so that she doesn't spread it. WHAT A CREATIVE STORY (joke)\

Edit: The first part's cutscenes ran at 2-3 fps (had to draw it frame by frame), but in part two, they run at 30fps constant (took me forever)
