Blackstorm

The Blackstorm is a non-canon weapon created by RC.

Overview
The Blackstorm, AKA the Black Hole Gun, creates a large singularity that will quickly drag all the zombies that are present on the map towards it, killing them upon impact with the singularity. It shoots out an black-blue orb-like projectile that has its own gravitational pull, which will head to the location where the weapon was pointed.

Pack-a-Punch
When Pack-a-Punched, the Blackstorm will become The Space Warper, which shoots black-red orb projectiles and as a result it increases the time of the singularity, plus the singularity field destabilizes upon the end, creating a large explosion.
