On the pages 7- 9 you see how the zombie is pierces by the spear.
Now can anyone tell me how the spear penetrated the zombie while only making a hole big enough for the tip of the spear to pass through but not wide enough for that cross section following the tip?
@Gusto:
Look at the zombie's shirt in pages 7+8.
The spear pierced it without making a hole larger than the staff part of the spear.
But the cross section must also have passed through it.
So I do not think that shirts have regeneration and hence I don't think it was regeneration.
@Talh I do agree it's a faulty and lazy ommision from the webcomic author. But if we're looking for potential reasons - it's a virtual game setting and there is a chance that it's built into the game engine.
