The PKE meter also got a major overhaul for the game. When pausing the game you can see that the PKE flies toward the screen sideways, suggesting that the PKE meter is now some sort of touch screen device. It also appears to store information on the ghosts on a database.
You can also see that the handle appears to be wrapped in a rubber grip. The PKE meter also displays in 3 different colours. Blue indicates that you’re close to a cursed artifact. Green means that you’re in an area of neutral or high level of PKE. Red means that you are honed in on a particular ghost or entity.
So far, no one has successfully replicated the game PKE meter, it would probably require programming knowledge to replicate the screen and functions seen on screen. People have attempted this using their iphones or smart phones.
As with the ghost trap, it is not necessary for you to have a game PKE meter when wearing a game style uniform. A movie style PKE is perfectly acceptable.
