Call of Duty: Black Ops

"A lie is a lie. Just because they write it down and call it history doesn't make it the truth. We live in a world where seeing is not believing. We live in a world where everything we know is wrong."

- Frank Woods in the world premier trailer (THIS GAME FUCKING SUCKS ONLINE< HARCORE FUCKING HOST MIGRATION 24/7


 * For the multiplayer faction, see Black Ops.

Call of Duty: Black Ops (also known as Black Ops, Cod 7 or simply BO) is the seventh main instalment of the Call of Duty series and was developed by Treyarch. The game was released on November 9, 2010.

Confirmation of the game's development was leaked by David Kim, a senior animator at Treyarch, in May 2009. Black Ops is set in various locations, including Vietnam, Russia, Laos and Cuba. Black Ops is grittier than previous games although the differences between Call of Duty: World at War and Black Ops are as significant as the differences between Call of Duty 2 and Call of Duty 4: Modern Warfare.

Campaign
The game begins with the main character in an interrogation room, strapped to a chair and surrounded by televisions and other electronics. A voice (Disguised, but obviously a man's voice) starts talking, and begins the interrogation. Mason is asked several questions, then begins to recall one of his first missions. This mission consists of Mason, Frank Woods, and Joseph Bowman attempting to assassinate Fidel Castro during the Bay of Pigs invasion of Cuba as a part of Operation 40. Mason succeeds in the assassination, but their extraction goes awry, with Mason staying behind to protect the extraction plane. He is captured by the real Castro and the Cuban military. Having formed an alliance with the Soviet Union, Castro hands Mason over to General Nikita Dragovich as a gift of their alliance. Mason is then held captive at Vorkuta Gulag, a Russian labor camp, for two years.

During his imprisonment, Mason befriends Viktor Reznov (a returning character from Call of Duty: World at War), a former Red Army soldier. Reznov recounts Mason the identities of those involved in Mason’s torture: Dragovich, Lev Kravchenko, and an ex-Nazi scientist who defected to the Soviet Union, Friedrich Steiner. All three share a connection to Reznov: in October 1945, Reznov, Dragovich, Kravchenko, and Dimitri Petrenko (protagonist of World at War Russia campaign) were a part of a unit sent to locate Steiner. Once Steiner is found, he leads Dragovich to a shipwrecked SS frigate, containing a nerve agent known as "Project Nova". Steiner tells the effects of the gas to Dragovich, but he wants to see first-hand what the gas does. Petrenko and two other Russian soldiers are locked in a room, then gassed while Reznov watches from a window. Reznov is spared when British SAS commandos attack. During the confusion, he destroys Project Nova. It is salvaged by the Russians, becoming known as "Nova-6." Shortly afterward, Reznov is imprisoned in Vorkuta for killing Russian soldiers during the escape from the ship. At Vorkuta, Mason and Reznov spark a prisoner uprising to escape the gulag, but only Mason escapes alive.

One month later, Mason is taken to the Pentagon with his new handler, Hudson. Mason is taken to President John F. Kennedy, who authorizes the assassination of Dragovich. In November 1963, Mason, Woods and Bowman are dispatched to Baikonur Cosmodrome in the Kazakh SSR to disrupt the Soviet space program. Russian-born CIA agent Grigori Weaver is captured during the operation and Kravchenko slices his eye while torturing him (from here on Weaver wears a patch over his eye socket as his eye is lost). The team save Weaver and eliminate members of the Soviet Ascension program. Dragovich eludes assassination, prompting Mason to search for him over the next five years.

By 1968, the SOG is deployed in Vietnam to investigate the Soviets' presence. After defending Khe Sanh, the SOG is deployed to Huế during the Tet Offensive to recover a dossier with information on Dragovich from a Russian defector. The team recovers the dossier, while Mason encounters Reznov, who is revealed to be the defector. The team later penetrates Laos to recover a Nova-6 shipment from a downed Soviet plane. The mission goes awry and the team is captured. They are taken to a POW camp, and forced to play Russian Roulette. Bowman is killed by a Spetsnaz operative while there. Mason and Woods escape, and regroup with their team. When Kravchenko is caught, he arms a grenade in order to kill the rest of the SOG team along with himself. However, Woods tackles him through a window, and only those two are killed. Meanwhile, in Hong Kong, Hudson and Weaver interrogate Clarke, an engineer who stabilized Nova-6 in Kowloon. Clarke identifies Steiner as part of the conspiracy, and reveals the location of a hidden facility in Mount Yamantau before being killed by Dragovich's men. Hudson and Weaver head to Mount Yamantau to destroy the facility and apprehend Steiner. During the mission, Hudson receives a transmission from Steiner requesting to meet him at Rebirth Island in the Aral Sea to learn how to halt a numbers broadcast with instructions to release Nova-6 gas in American cities. Meanwhile, Mason and Reznov head to Rebirth Island to assassinate Steiner. Mason believes he saw Reznov execute Steiner, but Hudson and Weaver witness Mason carrying out the deed. Hudson tackles him to the ground, and uses Mason's ASP to pistol-whip him in the head, knocking him out cold. Although not seen, he is taken away to be interrogated, beginning the whole cycle of events from the start of the game.

At this point, Hudson and Weaver are revealed as Mason's interrogators. Hudson realizes that Dragovich brainwashed Mason to understand the numbers broadcasts, effectively becoming a Soviet sleeper agent. Out of options, Hudson deliberately sets Mason free in order to follow him. It is revealed that Reznov died during the Vorkuta break out, and Mason’s visions of Reznov are a result of a personality disorder, a byproduct of Reznov having sabotaged Mason’s brainwashing program. Mason was supposed to assassinate Kennedy, but Reznov reprogrammed him to track down and kill the three men responsible for Dimitri Petrenko's betrayal and death. Mason deciphers the numbers, revealing the location of the Russian cargo ship Rusalka off the coast of Cuba.

By dawn, the team launches an assault on the Rusalka, with Mason and Hudson infiltrating an underwater broadcast station protected by the ship, a Soviet submarine station intended to be used as a staging point for US invasion after the planned Nova-6 attack. Confirming that the Rusalka is the numbers station, Hudson calls in the US Navy to destroy the ship and its underwater base. Mason and Hudson finally kill Dragovich in the lower levels of the station, and swim for the surface during the destruction of the targets, while Reznov's disembodied voice congratulates Mason. Weaver declares victory, but Mason says it is only for now. The story then cuts to a numbers broadcast and then to archive footage of President Kennedy prior to his assassination, with the broadcaster narrating the number sequence and Mason narrating certain numbers and words. Mason's final sayings relate to the assassination of Kennedy, for example, he says "22" which was the day that Kennedy was killed, and "6.5", which was the caliber of the bullet used to kill Kennedy. After a second play-through of the archive footage, Mason’s final words, as well as his presence in the crowd greeting Kennedy's motorcade, suggest that he assassinated Kennedy or that he assisted Oswald in assassinating Kennedy. This theory is supported by Dragovich sarcastically asking "Tried?" before he is killed when Mason says he made him try to kill his President. Note that Kennedy's assassination happens before the events of S.O.G. and after Executive Order, when Mason spends 5 years hunting Dragovich.

Zombies
Call of Duty: Black Ops features the return of Zombie Mode from Call of Duty: World at War. It is now the only Co-op mode in Black Ops as opposed to World at War, where it was found within the Co-op menu. There are three different Zombies maps available to all players.

The first is Kino der Toten. It is the only map unlocked by default. Kino Der Toten features the cast from the World at War maps Der Riese and Shi No Numa facing off against the zombie horde in an abandoned theater.

The second map is named "Five" and is unlocked either by completing the campaign on any difficulty setting or through a computer 'cheat' code using the terminal in the main menu. "Five" is set in The Pentagon, where the four playable characters are John F. Kennedy, Richard Nixon, Robert McNamara and Fidel Castro.

The last 'map' in Zombies is called Dead Ops Arcade. This is not typical Zombies gameplay: instead, it is an arcade style shooter similar to downloadable games found on services such as the PlayStation Store or Xbox Live Marketplace. It is a top-down shooter game in an open environment instead of the first-person shooter style of the other maps.

All of these maps/modes can be played in Solo, Two-Player Split Screen or Four-Player Online Mode. The Prestige and Hardened editions of Call of Duty: Black Ops also feature the four original Nazi Zombie maps from Call of Duty: World at War upgraded with the Black Ops engine, new weapons, and other additions such as dive to prone.


 * "Five" may be unlocked by going to the computer console and typing '3ARC UNLOCK' or by beating Campaign Mode on any difficulty.
 * Dead Ops Arcade is unlocked by going to the computer console and typing 'DOA' or '3ARC UNLOCK', which unlocks all Zombie Maps.

New features
While still following the same leveling-up features as the three previous main Call of Duty titles, Black Ops' multiplayer has many new features.

Instead of unlocking weapons, equipment and perks by leveling up, CODPoints are introduced. To purchase everything the player would like in Multiplayer, CODPoints must be spent. This currency is earned through regular gameplay, as well as from leveling up and completing Contracts. However, certain items become available only when the player has reached a certain level.

Another new feature is the Playercard. It details players' progression through multiplayer, allowing viewing of in-depth stats, ranging from Kill/Death Ratio to the number of times a player has used a certain Killstreak reward. It also links to recent games players have taken part in and from there links to the Theater. Players can view their friends or recently-met players' Playercards and also interact with their statistics. Emblems make a return from Modern Warfare 2, though instead of unlocking them through gameplay, they are completely uniquely customizable, allowing up to 12 different layers of different images, which are bought with CODPoints. However, layers are not lost through prestiging

The Theater is also introduced in multiplayer. It allows players to watch their own recent games, allowing a free spectate of the entire map while the game plays, as well as recording and uploading 30-second segments to the internet. It also allows players to spectate any other player who played alongside or against, while watching the gameplay. 100 games are stored in "Recent Games".

Recurring features
Leveling up still is a major part in the game; weapons are unlocked through progressing levels, but still need to be bought. Players unlock all Perks, Grenades, Equipment at level four, along with Create-A-Class.

The highest level attainable is 50, and when level 50 is completed, Prestige Mode is offered. There are 15 levels of Prestige, instead of the more regular 10, seen from Call of Duty 4: Modern Warfare onwards.

Customizable Killstreaks also make a return, however a main difference from Modern Warfare 2 is that the Killstreak rewards do not make an addition to their users' current streak, meaning unlocking higher killstreaks is more difficult as they are only unlocked from weapon, melee, grenade and equipment kills.

There are also now regional filters involved in matchmaking. Users can select whether they'd like the game to find a host from all over the globe or having a local host at the expense of time searching for games.

Split Screen online for Xbox 360 and PS3 players is implemented in Black Ops.

The Wii version of the game includes in-game voice chat. This is the first Call of Duty title to include the voice chat feature for the Wii. Nintendo and PDP have partnered to release the first headset to be used with the Wii known as PDP's Headbanger Headset.

It is possible to censor the game through the option. This returns from World at War.

It is possible to enable gun twisting only on the Wii version much like MWR.

Combat Training
Combat Training is a new Game-mode in which players battle against AI opponents. It is intended to help players who are new to multiplayer or players who want to try out new tactics. Players can adjust the AI opponents difficulty to Recruit, Regular, Hardened or Veteran much like the single-player campaign. It can be useful for trying new loadouts, as it is easy to get a lot of kills, getting high killstreaks that are normally difficult to acquire in multiplayer, and consequently a lot of money and XP by playing with a large amount of AI on a low difficulty setting, on a small map such as Nuketown or Firing Range

Contracts
Contracts are a new system in addition to the classic challenge system in Black Ops. A player is able to buy a contract with CoD Points, which will then direct them to complete an object. Completion of a contract will yield a higher CoD point payout than what was originally paid for the contract itself.

Wager Matches
A new mode with a separate ranking structure than the standard online modes allows players to gamble with their money. However, only the top three will receive the prize. They will be able to choose the buy in of 10, 1000 or 10000, and also which game mode to play of following (when buying in with 10000, the game mode is random):


 * One in the Chamber - each player is given a pistol with one bullet and a knife. For each kill achieved the player will receive one more bullet. However, each player will only have three lives.
 * Sharpshooter - all players are given the same weapon, selected randomly. Every 45 seconds, a new weapon is selected at random and used by all. Kills will award the player with perks and score multipliers.
 * Sticks and Stones - each player receives only a crossbow, ballistic knife, and a tomahawk. The catch in this gamemode is that if a player is killed with a tomahawk they lose all their points.
 * Gun Game - players start out with a pistol. For each kill with their main weapon players move up a level, granting them a better gun. First person to achieve kills with all 20 weapons wins. However, someone who is knifed will move down a level.

Create a Class

 * Create-A-Class 2.0 allows players to customize their appearance in addition to their load-out. Players may see what their character looks like while choosing a class, as the player's basic appearance will be determined by their Tier 1 Perk. Players are also able to choose a Face Paint pattern.
 * Some sights such as the Red Dot Sight can use custom reticles which includes choice of shape, as with lens and shape colors.
 * Gun camouflages are far more numerous than in previous Call of Duty games.
 * Players now have the ability to engrave Clan Tags and Emblems onto their guns.

PC-only information

 * The PC version of Call of Duty: Black Ops features dedicated servers.
 * Modding tools and the leaning feature have returned.
 * The PC version uses Steam as DRM and is using VAC as an anti-cheating tool.
 * Players can choose a server via a server browser screen or use matchmaking to send a lobby to a server chosen by the game.
 * Dedicated servers must be rented.
 * Unranked servers are completely customizable while ranked ones let the renter choose levels and gametypes.

Console-only information

 * Treyarch has claimed that it will be close to impossible to use any kind of mods or glitches in Call of Duty: Black Ops. Examples would be...
 * 1) Glitchers can be permanently banned.
 * 2) Hackers will have their stats reset, and will be permanently banned.
 * 3) Offensive emblems can result with a permanent ban.
 * Matchmaking has been changed so that it is easier for friends to play together, as there is now an in game friends list.

Private Matches

 * Players can customize private matches to a much larger extent then any previous titles of Call of Duty.
 * Custom games can be uploaded to the player's file share for the community to play
 * Players can create custom classes for the people playing the match to use.
 * Players can customize the killstreak awards granted to the people playing the match, both changing the reward and killstreak need to attain it.
 * The points system can be customized, including the points gained from kills, headshots, suicides and knives.
 * The health system, weapon power, and explosive power can all be customized separately.

Achievements & Trophies

Nintendo Wii Version
The Nintendo Wii version was also made by Treyarch, and has most of the features of its PS3/360/PC counterparts. There are, however a few omissions due to the limitations of the Wii console itself. They are: Treyarch has also made a few firsts for Wii Call of Duty, or Wii FPS games in general. These are:
 * Mission #9, "Crash Site" has been shortened. The player can only steer the boat in the first part of the mission. The rest is unchanged.
 * Mission #15, Redemption has been shortened. Instead of engaging enemies from the chopper, the chopper simply drops Mason and Hudson off. The rest is unchanged.
 * Dead Ops Arcade is not featured in the Wii version.
 * The Zombie map "Five " is also missing from the Wii version.
 * The Flamethrower weapon attachment is missing in Multiplayer.
 * The Valkyrie Rockets, Chopper Gunner, and Gunship killstreaks are all missing due to RAM limitations.
 * Theater Mode is missing due to RAM limitations.
 * Ground War is missing, on account of the Wii only being able to handle Black Ops Online with 10 players at the most.
 * Reticule Customization, Clan Tags, Customizable Playercards, and Emblems are all missing due to the large amount of RAM it would use up.
 * As usual with Call of Duty games made for the Wii, killcams and final killcams are both missing due to RAM limitations.
 * Private Matches are not completely customizable. They are about on par with Modern Warfare 2 private match customization.
 * The Camera Spike equipment is missing in Wii version.
 * Downloadable Content in the forms of live fixes, title updates, and map packs.
 * VoIP Chat Headset for Voice Chat.

Nintendo DS Version
A Nintendo DS version of Black Ops version was released on November 9, 2010. The game was developed by n-Space, the developers of the previous three Call of Duty DS games.

Controversy
Cuba has condemned the release of the game as it has special forces trying but failing to kill a young Fidel Castro, killing instead a body-double. The Cubadebate website said the game "encourages sociopathic attitudes of American children and adolescents, the main consumers of these virtual games".

Adam Biessener questioned events depicted in the single-player campaign stating that they push "the lines of good taste." Specifically noted was the scene depicting the torture of a restrained prisoner.

In Germany, the game was expected to be banned from public sale the end of November due to graphic violence, leading to removal of all promotion and the game itself from public displays in stores, so only adults can buy it on request.

The Federal Department of Media Harmful to Young Persons also received an "urgent request" to ban all international versions of the game based upon the "Nazi content". Videogames are not treated as art in Germany, thence Black Ops is classified as propagation of Nazi-ideology.

Secret Code
thumb|300px|right|Maverick Code

If the player decodes the NATO codenames (X-ray, Sierra etc.) into their first letters, and changing the serial numbers into letters (A-1, B-2) in the beginning of each level, and removing all the Xs, the player will get this message, "Reznov is dead, or is he dead, there was no body, not what he says he is". This has been nicknamed 'The Maverick Code' due to the Youtube user 01MaverickTen10 being the first player to crack the code.
