Meaning : This stupid "script" that i made replace most of the common infected by women, the ratio is now about 80% of women in the game. Also works for other players in the game. You can now play it like the iranian police and kill all these underweared women. :)

Setup : Replace the content of the [steaminstalldir]\left 4 dead\left4dead\scripts\population.txt file with the following text.

Limitation : You have to host the server.
