TF2 Freak Fight, Heavydile VS Sewer Medic

After nine months in development, hopefully, it will have been worth the FAT.
Seriously though, I'm really sorry this was so overdue. Anyway, for this episode, Sewer Medic (created by gb7zone7) must defend his turf from Heavydile (created by TrexHunter2000). In this battle to the death, who will emerge the victor?
