The Carvings On The Walls...

[ZombicidalManiac]

In Call of the Dead there are several of the same carvings on the walls of the PhD Flopper room. It looks like a figure with horns...but I can't really say for sure what it is. Its 2 vertical lines that are connected by a half circle at the top. On the half circle, there are two of what appears to be horns. The halfway up the two verticle lines are 3 horizontal lines. It's evident that these are carved in the wall which means that there may be other carvings in other walls throughout the map. That must mean that the funny shapes in the ice wall by the spawn are really carvings and not just random graphics like some people have said. I'm curious to find out what all this stuff is.
