Is this not actually a bug or has someone else run into this Is there a way to get past the scrake I have the same experence, its always a scrake that cant die, and mostly commen in weekly game mode. In the original version, they were not much different from Clots, but their unimplemented 2.0 form had them equipped with shotguns that they would randomly fire. just doesnt die.The game will last about half an hour on a single wave with just the scrake. Unlike the Wretch which was ultimately replaced by the Siren, the Infected Soldier was originally intended to still appear in 2.0 and can be found in the game files. The Infected Soldier was a specimen that appeared in the early versions of the original Killing Floor Mod, but it was removed in version 2.0.
