The Intervention is a sniper rifle that appears in some fanon maps.
A Darker Shade of White[]
The Intervention appears in A Darker Shade of White as a Mystery Box weapon.
Effectiveness[]
Like most sniper rifles, it is quite inefficient. However, it has higher penetration than other sniper rifles, and can go through a lot of zombies. However, it is pretty useless in close combat.
Bolter[]
When Pack-a-Punched it becomes the Bolter. It gets a damage boost, less sway and is also more accurate when hip-firing. It also comes with more ammo.
Popper[]
When Super Punched it becomes the Popper. It gets another damage boost, even less sway, even more hip-fire accuracy. You also gain a variable scope, a larger clip and more ammo.
