Ray Gun

"Do you like my glowing green balls?"

- Edward Richtofen

The Ray Gun is a Wonder Weapon which appears in Call of Duty: World at War, Call of Duty: Black Ops and most recently Call of Duty: Black Ops II. It is one of the most iconic Zombies features in the game, due to the fact that it appears in every Zombies map.

Zombies
The Ray Gun is available on all Zombies maps in Call of Duty: World at War, available only in the Mystery Box. The Ray Gun is often the most favored weapon in Zombies due to its ability to kill in one shot until rounds 18 to 22, or 22 to 25 when Pack-a-Punched, and its large magazine capacity for such a high-damage weapon. It is pinpoint accurate, meaning that the player should aim their shots very carefully, especially since it takes a small but noticeable amount of time for the shot to reach its target. The Ray Gun can hold 20 shots (40 when Pack-a-Punched) inside its magazine, which is, strangely, stuck into the barrel; the magazine seems to be two batteries stuck together with electric tape.

A document from Dr. Vannevar Bush reveals more about the Ray Gun. The document reveals that the Ray Gun is powered by Element 115, which must be contained in the Atomic Cold Cell batteries inserted into the gun as ammunition.

Campaign
The Single Player mission Little Resistance also features the Ray Gun as an easter egg. After using the first artillery strike, head onto the beach. Starting from the far right side, there are three puddles. Go in and out of these in the order of right, middle, left until the player reaches the last puddle. Stay in this puddle for 10 seconds. After that, the ground will shake and then the player should hear a voice (you cannot make out the language, nor what it is saying). Four Shisa statues will arise from the ground holding a Ray Gun. To get it, walk up to any of the four statues and then press and hold the action button. The gun has maximum ammo, and the player can come back to the statues and get a new Ray Gun an unlimited amount of times. It can be used to destroy enemy tanks with two shots at the end of Little Resistance instead of calling an artillery strike. It has the ability to burn the ally/enemy bodies when they are dead.

Call of Duty: Black Ops
The Ray Gun is available in Call of Duty: Black Ops in all the maps in Zombies game mode. While still being very powerful (one-shot-kill up to round 15), the gun has a tendency to start making crawlers on rounds 18 more often if shot in the legs. Although this can be very useful, the player may be caught unaware by them. At about round 23, the Porter's X2 Ray Gun (the upgraded version of the Ray Gun) will start to make crawlers. One problem is that it makes a mere 50 points per kill, making it one of the worst weapons to make points with. The Ray Gun, along with the other Wonder Weapons, is very useful on Kino der Toten, "Five", and Moon, as crawler zombies will not release their toxic gas if killed with it. It becomes useless at later rounds, since it takes a lot of ammo to kill a zombie and ammo is low. Also, the splash damage can be lethal to the player if fired at a zombie close to the player, unless they have PhD Flopper.

Call of Duty: ZOMBIES
The Ray Gun also makes an appearance in the Call of Duty: ZOMBIES application for the iPhone, with a few differences from its counterpart on the console. It causes no splash damage to the user and loses its one- shot kill abilities earlier (compared to World at War), at round 17 for Verrückt and Nacht der Untoten, and round 20 for Der Riese and Shi no Numa. Along with these differences, it is not fully automatic on the iPhone. Obtaining it on the iPhone gives the player the "Space Man" achievement, and using it to kill 100 zombies gives the player the "Laser Face" achievement. It also causes no aesthetic damage to zombies, and cannot make crawlers. The Ray Gun reappears in Call of Duty: Black Ops ZOMBIES. Although it was not released with the game, it was added in with an update on February 2 along with the Monkey Bomb.

Call of Duty: Black Ops ZOMBIES
The Ray Gun returns to Call of Duty: Black Ops ZOMBIES. It was not released with the game but an update added the Ray Gun on February 2. It can be found in the Mystery Box on Kino Der Toten or in Dead Ops Arcade as a Power Up. It has many of the same features of the Ray Gun in Call of Duty: ZOMBIES. One similarity is that the Ray Gun isn't full auto in both games.

Call of Duty: Black Ops II
The Ray Gun returns again in Call of Duty: Black Ops II. It was first seen in the Teaser Trailer being used by an unseen survivor inside of the bus when it was passing into a tunnel.

Porter's X2 Ray Gun
When upgraded in the Pack-A-Punch Machine, the Ray Gun becomes the "Porter's X2 Ray Gun." With the upgraded version, the magazine capacity is twice as big, the spare ammo is increased from 160 to 200, it gets extra damage through damage multipliers, it shoots red-orange rays instead of green, and the splash damage is reduced. Also, should a player get downed with a Porter's X2 Ray Gun, he or she will have a larger amount of ammo to cover teammates.

The Porter's X2 Ray Gun gets its name from H. Porter, the scientist that was working on the next Ray Gun model. He was trying to reduce its peripheral damage and apparently succeeded if the Porter's X2 Ray Gun is really the second generation model he created. H. Porter is a reference to Max Porter, the programmer that created the Ray Gun.

Ray Gun vs. Porter's X2 Ray Gun (Black Ops)
Almost exactly the same as its World at War upgrade, the Porters X2 Ray gun features more damage, everything else is more or less equiveleant to its predecessor.
