Getting the screamer mixed up with the infected is like getting the witch mixed up with a dead regular zombie
When i get attacked by a female zombie, the ones that wear clothes that look close (color-wise) to the Witch's, i keep thinking the Witch is beating me up, but i'm wondering why she didn't incapacitate me, until i see the hands aren't big red sharp things and he doesn't look as creepy as the Witch :o
