Concept are for the splash page of the manual design, featuring Tammy post-infection.
Some quick digital artwork was put together for the concept. The main character was named Tammy, a reference to the movie Fido, and all concept artwork was based off of roller derby girls. Her primary weapon was a giant mallet (a trope within anime and japanese RPGs). Here is a drawing of said character prior to infection, post-zombie killing.
The Zombiegotcha code, written in its entirety by Travis Goodspeed, was released to the public for further revisions in the hopes that the project would continue. At this point it has been handed into the capable hands of Christiane Ruetten. The code is available for download from Sourceforge.
