Hi!
I complete the idea that the player can rub himself in zombie remains:
*The first few times you do it, it makes you nauseous.
* If you have a delicate stomach, you may get sick.
* If the player does not change dirty clothes, they cause dizziness and nausea after a while.
* After a certain time, the "camouflage" effect is lost
... I apologize if my English is not very good ...
