Ray Gun

"Do you like my glowing green balls?"

- Edward Richtofen

The Ray Gun is a wonder weapon featured in Call of Duty: World at War, Call of Duty: Black Ops, Call of Duty: Black Ops II and Call of Duty Online. It is one of the most iconic Zombies features in the game, due to the fact that it appears in every Zombies map and is the first wonder weapon created by the illustrious Group 935. A direct successor to the Ray Gun, known as the Ray Gun Mark II, appears in every Zombies map of Call of Duty: Black Ops II with the Vengeance downloadable content.

Zombies
The Ray Gun is available in 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 ammo 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 rounds (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.

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. Next, on the far right there is a puddle. Get into the puddle and then move on to the next puddle in the general middle of the shore. Then, just stay in the far left puddle about 10 seconds. After that, the ground will shake and then the player should hear a Japanese-like voice. Four 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 start with maximum ammunition, and the player can come back to the statues and get a new Ray Gun an unlimited amount of times.

The player can get the Ray Gun as a tertiary weapon by holding the radio to get it. By doing so, the player will lose the ability to call the rocket strike. To prevent this, call a rocket strike then immediately get the Ray Gun from the statues before the radio hand-off. After that, the player should have three guns and have the radio back after the count. This trick can be done again if players wishes to acquire different guns by replacing the Ray Gun to other guns they do not have.

The Ray Gun can be used to destroy enemy tanks with two shots at the end of "Little Resistance" instead of calling an artillery strike. It also has the ability to distort dead bodies.

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 and higher more often if shot at the legs. Although this can be very useful, the player may be caught unaware by them and blocked/surrounded. At about round 23, the Porter's X2 Ray Gun (the upgraded version of the Ray Gun) will start to make crawlers. Occasionally, the reticle when you aim down the sights can change colors from red, green, purple, white, yellow, and blue. One problem is that it makes a mere 50 points per kill, making it one of the worst weapons to accumulate points with. The Ray Gun, along with the other wonder weapons, is very useful on Kino der Toten, "Five", and Moon, as Gas Zombies will not release their toxic gas if killed with it. It remains relatively powerful at later rounds, but runs out of ammunition quickly. Also, the splash damage can be lethal to the player if fired at a zombie or an object close to them, unless they have PhD Flopper.

A document from Dr. Vannevar Bush reveals more about the Ray Gun. The document reveals that the Ray Gun was developed by Dr. Ludvig Maxis of Group 935 and was based on designs seized from the Rising Sun Facility in Japan. It is powered by Element 115, which must be contained in the Atomic Cold Cell batteries inserted into the gun as ammunition.

Call of Duty: Zombies
The Ray Gun also makes an appearance in the Call of Duty: Zombies application for the iOS, with a few differences from its counterpart on the consoles. It causes no splash damage to the user and loses its one-shot-kill ability earlier (compared to Call of Duty: 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 iOS version. Obtaining it on the iOS version 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.

Call of Duty: Black Ops Zombies
The Ray Gun returns in 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, Ascension, Call of the Dead: Director's Cut, 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, the only difference is that in this game, the Ray Gun is not as well textured. One similarity is that the Ray Gun is not fully automatic in both games.

Call of Duty: Black Ops II
The Ray Gun returns again in Call of Duty: Black Ops II, again with a new look. Its performance is identical compared to previous games, however, it now seems to have a reduction in splash damage against the player. The Ray Gun now has a new sprinting animation and dive-to-prone animation. The only real difference between the Call of Duty: World at War and Call of Duty: Black Ops versions of the weapon is that it has a much higher chance of being gained from the box, as there are no other wielded wonder weapons available in the game, akin to the first Zombies map, Nacht der Untoten. Furthermore, it has received a graphical update. However, the Ray Gun does not appear and is not available in the Grief maps Town and Farm. The Ray Gun sometimes does not change colors when Pack-a-Punched. It may retain the original colors instead of the Pack-a-Punch skin on the weapon.

Call of Duty Online
The Ray Gun makes another appearance in Call of Duty Online, in the Dead Rising game mode.

Porter's X2 Ray Gun
When Pack-a-Punched via the Pack-a-Punch Machine, the Ray Gun becomes the Porter's X2 Ray Gun. With the upgraded version, the magazine capacity is doubled, the reserve 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, they 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.
