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, where only a few know what really happened. We live in a world where everything you know is wrong."

- Alex Mason in the world premiere trailer.

Call of Duty: Black Ops, abbreviated as CoD: BO or simply BO, is the seventh main Call of Duty game, and the third main game of the series developed by Treyarch. The game was published by Activision and for PC, Xbox 360, PlayStation 3, and the Nintendo Wii. Officially announced on April 30, 2010, the game was released on November 9, 2010. It is also considered a sequel to Call of Duty: World at War due to its main storyline being based on the events of Viktor Reznov after World War II.

Gameplay
Call of Duty: Black Ops differs from most previous installments, which would involve a usual three-country campaign while Call of Duty: Black Ops features two playable countries (Russia and the USA), but only has an American campaign. Gamers play from the perspective of Captain Alex Mason of the MACV-SOG, Jason Hudson of the CIA, and Russian-born soldier Viktor Reznov of the Red Army. The game also introduced several new features such as dive-to-prone and the available use of a flashlight on certain weapons. Furthermore, the campaign's playable characters now speak while being controlled by the player.

Plot
Much of the Call of Duty: Black Ops campaign is told through the eyes of SOG and CIA operative Alex Mason, primarily through flashbacks. Mason is asked questions by an unknown interrogator about a numbers broadcast which is being used to contact Soviet sleeper cells in the United States. These questions set the stage for the campaign missions.

The first mission is a flashback to Mason's participation in the Bay of Pigs Invasion, a doomed effort to assassinate Fidel Castro. At the end of this mission, Mason is captured by Castro's soldiers and given to Nikita Dragovich as a 'gift.' He is held captive at the Vorkuta Gulag, a Russian labor camp, for two years.

After further interrogation, Mason recounts how, during his imprisonment at Vorkuta, he befriended Viktor Reznov, a former Red Army soldier and a returning character from Call of Duty: World at War. Reznov assists Mason in sparking a prisoner uprising at Vorkuta, which facilitates Mason's escape from the prison.

One month after his escape, Mason is escorted to the Pentagon with his handler, Jason Hudson, where he receives authorization from President John F. Kennedy to assassinate Dragovich. He is then dispatched with Frank Woods and Joseph Bowman to Baikonur Cosmodrome in the Kazakh SSR to sabotage the Soviet space program. The team saves a captured operative and destroy the Soyuz 2 as it is launched. Dragovich, who is present at the launch, escapes alive, forcing Mason to spend the next five years searching for him.

By 1968, the SOG, including Mason, is deployed in Vietnam to investigate the Soviet presence. After Mason helps defend the military camp at Khe Sanh, he is deployed to Huế during the Tet Offensive to recover a dossier with information on Dragovich from an unnamed defector. The team recovers the dossier, and Mason discovers that Reznov is the defector.

After Mason escapes Huế City, the campaign shifts to a mission in Kowloon, Hong Kong, where Hudson is sent to find and interrogate Dr. Clarke, a scientist working under Dragovich. The mission goes awry, and Clarke is killed while Hudson seeks to escape Dragovich's men.

Then, after further interrogation, Mason reveals the story, as told to him by Reznov, of the history behind Dragovich, his associate, Lev Kravchenko, and German ally, Dr. Friedrich Steiner. These events take place shortly after World War II, and are told through the eyes of Viktor Reznov. They detail Dragovich's discovery of the German chemical weapon, Nova 6, and illustrate his ruthlessness as he murders his own soldiers to witness the effects of the weapon, including Reznov's close friend, Dimitri Petrenko. This mission ends with Reznov asking Mason to promise him that Petrenko's death will be avenged, and Dragovich, along with his allies, Kravchenko and Steiner, will be killed.

The interrogation moves back to 1968, and Mason describes how he and the rest of his squad from the SOG fight their way through Viet Cong-controlled territory in an ultimately futile attempt to chase an elusive Kravchenko, and are later sent to locate and investigate a downed Soviet plane containing Nova 6. During this investigation, Mason, Woods, and Bowman are captured by the Viet Cong.

Again, the perspective switches to Agent Hudson, who is sent on a mission to infiltrate a Soviet base in the Ural Mountains, a suspected development center of Nova 6. The control room the facility is rigged with explosives in a trap set by Dragovich, but Hudson's team is contacted remotely by Dr. Steiner, who gives his location and promises, in exchange for safety from Dragovich's systematic elimination of "loose ends," information on cracking the numbers broadcast.

After this mission is completed, Mason describes to his interrogator how Bowman was killed while imprisoned, and how he and Woods escape from their Viet Cong captors. Mason fights across a vast swath of Vietnamese land in a stolen Mi-24 Hind to reach Kravchenko's base. At this base, Mason again meets Reznov, who leads him through the base towards Kravchenko. When Mason reaches Kravchenko, Kravchenko (supposedly) commits suicide with his bandolier of grenades, seemingly killing Woods in the process. Mason and Reznov then recover documents that lead them to Rebirth Island.

Mason's story converges with Hudson's at Rebirth Island, as both fight their way through a Soviet Nova 6 research and production facility to reach Dr. Steiner. Hudson engages in an all-out assault on the facility with light armor and a squad of CIA operatives, while Mason sneaks into the facility with Reznov. Mason reaches Steiner only shortly before Hudson, and watches as Reznov murders Steiner.

However, when the same story is retold through Hudson's eyes, it is revealed that it was, in fact, Mason alone who shot Steiner, while exclaiming that he was Reznov and would have revenge. The flashbacks end and the interrogation continues. Hudson reveals himself to be the interrogator and confronts Mason face-to-face in a desperate bid to break him free of his brainwashing. In this mission, it is revealed that, while at Vorkuta, Mason was subjected to severe mental reconditioning in order to turn him into a sleeper cell who would perform Soviet missions in America. However, Reznov 'hijacked' this conditioning and used it to instill in Mason an absolute devotion to complete Reznov's vow for revenge. Reznov was actually killed in the escape from Vorkuta, and, therefore, all subsequent appearances of his character are merely a part of Mason's imagination, brought on by the intense nature of the brainwashing Mason experienced.

As the reprogramming of Mason's brain is finally broken, Mason recalls the origin of the numbers broadcast, a ship off the shore of Cuba called the Rusalka. In a CIA raid on the ship and the underwater broadcast station over which it is anchored, Mason strangles Dragovich to his death and sinks the broadcast station, ending the threat that the sleeper agents presented to the United States.

Multiplayer Theme Song

New features
While still following the same leveling-up features of the three previous main Call of Duty titles, Call of Duty: 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 Call of Duty: 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".

As a minor addition, most of the maps have ambient activity or noise in the background, and/or interactive items, such as the train on WMD, or the doors in Radiation. Before, most multiplayer maps either had limited background activity, such as Carnival from Call of Duty: Modern Warfare 2, or no background activity at all.

Ranks
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.

Returning features
Customizable Killstreaks make a return, however a main difference from Call of Duty: Modern Warfare 2 is that kills from 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.

Included is the option to censor the game, removing much of the foul language in the campaign and gore. This returns from Call of Duty: World at War. Unlike Call of Duty: World at War, censoring the game does not prevent the foul language from being said in the campaign.

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. Higher difficulty settings increase the AI's ability to detect others and fire. Recruit and Regular AIs react poorly or not at all to be fired upon, and are unaware of players sneaking up on them. They aim slowly onto their target, firing slowly. Hardened and Veteran AI use all their resources to detect enemies, and aim and fire quickly upon targets. Combat Training 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 Call of Duty: Black Ops. A player is able to buy a contract with CODPoints, which will then direct them to complete an objective. Completion of a contract will yield a higher CODPoints payout than what was originally paid for the contract itself. However, there is a time limit to complete a Contract; if the time limit expires, then no CODPoints are given.

Wager Matches
A new mode with a separate ranking structure than the standard online modes allows players to gamble with their CODPoints. 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 an M1911 with one bullet and a knife. One hit from any weapon will kill a player. 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. Consecutive 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 game mode is that if a player is killed with a Tomahawk they lose all their points.
 * Gun Game - Players start out with a Python. For each kill with their main weapon players move up a tier, granting them a better gun. First person to achieve kills with all 20 weapons wins. However, someone who is knifed or commits suicide will move down a level. Killing someone with the knife will not advance them a tier.

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 and their faction. Players are also able to choose a Face Paint pattern.
 * Some sights such as the Red Dot Sight can use custom reticules 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.

Perks and Killstreaks

 * The AC130 might have been planned to be a killstreak, but it was scrapped, supported by _ac130.gsc found in the game files.

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 game types.

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. But it is not impossible, recently mods were released on the PlayStation 3, possibly Xbox, that allows you to gain a large amount of XP in certain games.
 * 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. Microsoft stated that using the Swastika symbol on the emblem will also result with a ban.
 * Matchmaking has been changed so that it is easier for friends to play together, as there is now an in game friends list.

 * Custom games can be uploaded to the player's file share for the community to play.

These include: Treyarch has also made a few firsts for the Nintendo Wii versions of Call of Duty. These include:
 * 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 Nintendo Wii version.
 * The Zombie map "Five" is also missing from the Nintendo  Wii version. Some players have entered "Five" by typing in "3ARC UNLOCK" in the computer; however, they stated it as "incomplete".
 * The Flamethrower weapon attachment is missing in Multiplayer probably due to the huge amount of framerate drop whenever anyone uses it in World at War.
 * The Valkyrie Rockets, Chopper Gunner, and Gunship killstreaks are all missing due to RAM limitations. Although the Valkyrie Rockets and the Gunship still appear in singleplayer.
 * High Definition quality is removed due to RAM limitations.
 * Theater Mode is missing due to RAM limitations.
 * Ground War is missing, on account of the Nintendo Wii only being able to handle Black Ops Online with 10 players at the most. Although hackers can increase this to 12 players.
 * Clan Tags, Customizable Playercards, and Emblems are all missing due to lack of time Treyarch's Wii team had to complete the Wii version.
 * 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 Cal of Duty: Modern Warfare 2 private match customization.
 * The Camera Spike equipment is missing in Wii version.
 * The missions "Vorkuta", "Executive Order", and "SOG" are divided into parts.
 * Most of the guns sound very different from the other consoles and the PC (ex. M1911 Sounds like the console M1911 from World at War).
 * Red Dot Sight or Reflex Sight cross-hairs cannot be customized.
 * Golden camouflage is more yellowish, and no shine. The synthetic parts that replace wood are also still wood. Most veteran players would commonly say it as "Mustard Camo"
 * The missions "U.S.D.D." and "Revelations" does not let the player control Mason, instead it is like a video clip. Most of the scenes on "U.S.D.D." are cut out.
 * So far, the Nintendo Wii has not received any map packs, but multiple patches.
 * All weapons can be tilted sideways with motion control, except rocket launchers. It can be disabled in the option menu whenever the player wants to.
 * All pistols and certain submachine guns are held with one hand because of weapon twisting.
 * The hip fire reticle can be customized if the player were to use a Wii Remote (cannot be done on a Classic Controller (Pro)).

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 singleplayer 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 at 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". Video games are not treated as art in Germany, hence Call of Duty: Black Ops is classified as propagation of Nazi ideology.

A school in Horsham, England, has banned any connection to Call of Duty: Black Ops. Any perpetrators are either put in detention or "fined". The children have voted against this but have lost due to its 18+ rating. The head teacher sent out letters in an attempt to persuade parents, complaining of the following: body bags being thrown by topless men, the feeling of blowing up a group of enemies with an RPG, the ability to kill Fidel Castro, swearing, gore, and so on. Although taking the risk, over 75 of the 425 children have bought and played the game despite the consequences.
