 * It lets the player to see the locations of perks, wall guns, chalk locations, the Pack-a-Punch and the Mystery Box wherever you are on the map.


 * It makes zombies occasionally drop small amounts of ammo and points, which disappear after a few seconds.


 * Will cause certain zombies to release green colored cloud of gas upon death, that will cause the player to be ignored by the zombies for a short period of time if they are standing in it.


 * The eyes of the Zombies will glow much brighter making them easier to see from a distance.
