More ammo, increased clip size, and it makes you shoot red lightning! 8)

it shoots out red eletrcity and it has more bullets and bigger clip

Might not be true but I noticed it has a farther range of who it hits

I forgot to add that the lightning spreads to more zombies.

6 in the clip and more ammo

There is 6 bullets per clip, I believe around 30 bullets total (instead of 18), shoots red lighting/electricity, kills more zombies per shot, and longer range/better accuracy, by far one of the best upgraded guns in the game.

the PaP machine does the same basic thing for everygun.
-increased damage
-increased clip size
-increased overal ammo
(true for MOST guns)

6 shots in a clip 30 shots of ammo shoots red turns silver has some design in places and transfers to more zombies when you shoot

it has 6 bullets in the clip and 36 total bullets. the shots are red and it does more damage.

what i noticed is that when you upgrade it, you can't save yourself with it anymore. with the normal one if you're getting attacked, you can shoot the attacking zombie to live. if you shoot the upgraded one, it just kills you because it's so strong.

so if you get it remember not to shoot too close to you just like the ray gun.
