Frank is about as old as a toddler I first developed the design back during my horror character map naming days in H4. I was able to complete werewolf and dracula but the limitations made it so may map inspired by half a quake arcade map impossible. I could honestly not tell you what map it was. It's been to long. The map focus as with most of my maps is to have good predictability and the promotion of pinching.
Also, the teleporters do not have the green chroma on them anymore.
