Particle Scrambler.
A sleek chrome gun that's scope goes into the gun, it has a glowing orb in the hole through the gun. It has a bolt on the back like the L96A1. It's barrel is to separate barrels in a double helix shape.
This snipers main ability is that the barrels start to spin and after 5 seconds a black beam will fire. If it hits a zombie the zombie will glow black and explode violently, killing all zombies in a 5 meter radius (this is OHK till round 20 ). If the beam hits a surface a hazy black dome will appear around in a 10 meter radius that gradually does damage s zombies until their health is at 1. It has a 5 shot magazine and reloads by taking the sphere out and putting in a new one. You cannot reload mid magazine and it has 35 reserve ammo. To emphasise on sniping any player caught in either effects will be instantly downed.
Gerches vengeance.
The pack a punched version of it has a darker chrome and the orb has a particle effect like the Gerche device portal. It has the two same abilitys as last time except now the black explosion and mist are purple instead. They are now both one shot kills till round 40. If a player is caught in the dome they will teleport to another part of the map. It's has the same amount of ammo and same mag size. The scope now has a variable zoom and the zombie explosion will still insta kill you.
