Nuclear Fusion Reactor-16

The Nuclear Fusion Reactor-16 (also referred to as the NFR-16) is an experimental wonder weapon introduced in RoachTheIntelCollector's "The Disaster" saga. It can obtained from the Mystery Box for 950 points.

Overview
The design of the NFR-16 takes a few aspects of the normal Ray Gun, except it looks more like an Submachine Gun. A small nuclear power core acts as the ammo, and every time the player reloads, the player ejects the core and replaces it with a new one. The barrel of the gun features two ray coils in a similar design to the Ray Gun. Uniquely, the weapon can be fired semi-automatically or the player can charge a shot, which takes two shots from its magazine. However, the weapon cannot be reloaded until all the ammo in the magazine has been depleted. It fires green blobs of nuclear acid, which sticks to zombies, causing them melt partially before exploding. If a charged shot is shot at the ground, it will create a pool of nuclear acid, which when zombies step on it, will die.

When upgraded via the Pack-a-Punch Machine, it becomes the Deatomizer-32, gaining an extreme damage boost, more ammo and shoots red blobs instead of the normal green.
