32, TCF Scientist. Status: deceased
Dr. Overbeck was a top ranking scientist working for TCF when the outbreak occurred. Though he would never live to find out, his work would go on to start a new branch of science called "Slagology." While getting attacked during "Project X", Overback mistakenly punched in the wrong settings and sent the TCF crew back in time to the year 1276, rather than the one year back that was intended.
