Emergency Nuke

About
Emergency Nuke is a Wonder Weapon in The Undead Lab Zombies map. It can be obtained via Mystery Box with 950 points. It kills all the current Zombies in the map. It has one benefit over the Nuke power-up: it kills all the zombies instantly. But the player who uses it should beware; the player doesn't get any points from using it. It only has one nuke in the mag, and one nuke in reserve.

Pack-a-Punched variant
When Pack-a-Punched, it becomes the Fat Boy Launcher. When used, it awards the player's team with 100 points, and has three nukes in reserve.
