The V-R11 is a Wonder Weapon that appears in Call of Duty: Black Ops. It debuted in the Zombies map Call of the Dead and is currently exclusive to it. It also plays a key role in the easter egg on this map.
The V-R11 is a very unique weapon. When a zombie is hit by one of the V-R11's beams, it will turn into a normal human. The human will be chased around by zombies, and he will scream while he is alive. He will run away from the zombies, heading towards the closest body of water and attempting to use the shortest route possible, freezing himself to death. Since he attracts zombies, he may be utilized similarly to a Monkey Bomb, but the zombies will only chase him if he is the closest person to them. If another player is closer, the zombies will go after the player anyway, effectively wasting some of the V-R11's scarce ammunition. If the player is at the correct stage of the Original Characters Trapped easter egg, then he will run to the base of the lighthouse instead. Because the human being will run to the water, the weapon is more effective the farther away the player uses it from the closest pool of water (such as the top of the lighthouse). Its cross-hairs are also unusually tight.
When Pack-A-Punched, the weapon is renamed the "V-R11 Lazarus." When it is upgraded, it fires red bursts, much like the Porter's X2 Ray Gun. The magazine capacity increases to six shots with the reserve ammo increasing to 18. Shooting George Romero with the V-R11 Lazarus while he is in a body of water will cause him to disappear into the water. If a player shoots a zombie three times with the V-R11 Lazarus, it will cause the zombie to explode, awarding the player with the achievement "Stuntman". A zombie shot with the V-R11 Lazarus will also attract George Romero.
The player can also shoot another player with the V-R11 or V-R11 Lazarus, giving them a red-tinted screen and having zombies ignore them, letting them revive other players without interference. The V-R11 Lazarus adds a temporary insta-kill to this affect. The player appears to have green or red (if upgraded) lightning coming out of his body, like George A. Romero, except different colored. The effect lasts longer when the V-R11 is Pack-A-Punched.
The V-R11 will also put George Romero into his "calm" state when he is angered and will anger him if he is calm. He will automatically be angered again after 10–15 seconds if he was calmed down with the V-R11. Players should use this time to escape or move into a body of water.
