CZ75

The CZ75 is a semi-automatic pistol that appears in Call of Duty: Black Ops and Call of Duty: Black Ops: Declassified.

Campaign
The CZ75 is first obtainable in the mission "Numbers", where it is Dual Wielded by Hudson at the start of the level. It can be obtained from the holsters of the Spetsnaz troops with no attachment, Dual Wield, Full-Auto, or both attachments. The player is also given one with no attachments at the end of the mission, where a knocked-down Hudson has to fend off attacking Spetsnaz soldiers until his pickup arrives. Clarke also wields a CZ75 (albeit holding it like a rifle) until he picks up his G11.

The CZ75 appears again in the missions "WMD", "Victor Charlie", "Payback", "Rebirth", and "Redemption" in the Spetsnaz troops' holsters.

In "Payback", the CZ75 is used by Mason to kill several VC soldiers while using another VC's body as a shield before regular gameplay starts, when it then becomes the held weapon.

In the mission "Redemption", Dragovich will use the CZ75 in an attempt to kill Mason. Hudson can also be seen using the CZ75 in this mission.

In these missions, it appears the same way it does in "Numbers", with all the same possible attachments. It is fairly powerful and accurate, especially for a pistol.

Multiplayer
In multiplayer, it is the "Classified" handgun, meaning it is unlocked by buying all other pistols (minimum level is rank 18, when the Python is available). It costs. It has a standard magazine capacity of 12 rounds, which is increased to 18 with the Extended Mags attachment. The weapon has gained a large amount of popularity as a sidearm online due to its relatively large magazine, and the ability to fire fully automatic. Note that the CZ75 has no idle sway with the Full-Auto attachment. While using the perk Second Chance and the Full-Auto attachment for the CZ75, the CZ75 will be replaced with the M1911 in Second Chance.

Players with fast trigger fingers should avoid the Full-Auto attachment, as it adds recoil, reduces damage and lowers the firecap. Instead, it is recommended that such a player use the Extended Mags, which may allow multiple semi-automatic kills before the need to reload. However, the Full-Auto attachment can prove invaluable to snipers, as it can give them a weapon that is useful for close quarters. thumb|300px|right|All attachments showcase for the CZ75.

Attachments

 * Upgraded Iron Sights
 * Extended Magazines
 * Dual Wield
 * Suppressor
 * Full-Auto Upgrade

Zombies
It is possible to obtain the CZ75 from the Mystery Box, either with the Dual Wield attachment, or without (except in the Wii version, where only dual wield semi auto can be obtained). It is present in all four original Nazi zombies maps and in 6 Call of Duty: Black Ops Zombies maps; however, it does not appear in Dead Ops Arcade. The normal CZ75 has the capability of 1-hit-headshot up to, and including, round four. With Dual Wield, it can be fairly effective up to around round 7 when firing at a single zombie or a large group. Due to its high reserve ammunition, if one pistol is fired at a time, so one reloads while the other is shot, fire can be sustained until the player runs out of ammo or gets downed. However, some players may dislike Dual Wield due to the inability to ADS. This limitation can be troublesome when confronting one or two zombies, but effective in a group of six or more. Against few zombies, many shots will miss and therefore be wasted, somewhat canceling out the advantage of the increased ammo.

If it is Pack-A-Punched with the Dual Wield attachment, they become Calamity and Jane (for the left and right pistols respectively). It receives the Full-Auto attachment, 20 rounds per magazine, more damage, and more reserve ammo. While it is very powerful and has a rapid fire rate, accuracy is still an issue that hinders medium to long range usage. The normal CZ75 when upgraded becomes Calamity by itself, a fully automatic variant. The Calamity's one-hit-headshot capabilities lasts up to, and including, round 11. It is recommended to swap this gun out for a more powerful gun in later rounds, as by round 20 it takes one or two whole upgraded magazines to kill a zombie. However, if going for headshots it can be an effective weapon until round 25 and higher, and if both magazines are used entirely with Dual Wield and most of the bullets hit, effective until round 30.

Call of Duty: Black Ops Zombies
The CZ75 appears in the iOS port, Call of Duty: Black Ops Zombies. It is available only in the Mystery Box. Unlike Call of Duty: Black Ops, the Dual Wield CZ75s are unavailable.

Trivia

 * The CZ75 is the cheapest weapon in Call of Duty: Black Ops multiplayer besides the Python and Ballistic Knife, costing only, as opposed to all other guns which cost . It is also the cheapest Classified weapon.
 * The CZ75 has the lowest rate of fire of any automatic weapon in Call of Duty: Black Ops, tied with the M60.
 * The CZ75 is the first Dual Wield weapon in Zombies when not Pack-A-Punched. It, along with the M1911, HS10, and PM63, are the first Dual-Wield Pack-a-Punch weapons.
 * The CZ75 is the first and so far the only pistol in the Call of Duty series to feature an option for Full-Auto fire. The closest other would be the G18 in Call of Duty: Modern Warfare 2 and the Kap40 in Call of Duty: Black Ops II.. However, it was classified as a machine pistol, and its automatic fire does not count as an attachment.
 * The Wii version does not have a single CZ75 in Zombies mode, but it is possible to obtain Dual Wield CZ75s.
 * The CZ75's Upgraded Iron Sights were originally misaligned, as pictured here.
 * CZ75 has "CT75" engraved on the frame. It is very easy to see on third person view of the pistol.
 * In "Redemption", "Numbers", and "WMD", the player might find a "CZ75 Full-Auto Dual Wield". Normally, weapons with two attachments read "Multiple Attachments" instead of being specific.
 * The CZ75 has a unique empty reloading animation among pistols. When the magazine is empty, the character pulls on the slide instead of using the slide release. It shares this trait with the G18 from Call of Duty: Modern Warfare 2 and the Five Seven from Call of Duty: Modern Warfare 3.
 * Occasionally while playing Nazi Zombies, when reloading Calamity and Jane the right gun has no reload animation. Instead, its slide will be stuck back until it is "reloaded". After, the slide immediately is shown cocked.
 * The name of the upgraded CZ75, "Calamity & Jane," is a reference to the Scout and Frontiers-woman, Calamity Jane.
 * As with the Python, the characters in Zombies give negative comments after they receive a normal CZ75 from Mystery Box.
 * When firing the Dual Wield Full-Auto CZ75s in Campaign, the recoil creates an unusual effect where the CZ75s are seemingly pushed below the player's field of vision. This is possible with most other semi-automatic guns as well, but only via modding unlimited ammo and a high rate of fire, especially in Call of Duty 4.
 * The Full-Auto CZ75 has another magazine under the barrel, instead of a grip. Also, the barrel is extended.
 * When looking at the rate of fire when Full Auto is attached, it just says "Fully Automatic".
 * Despite being the same guns, the single CZ75 and Dual Wield CZ75 in Zombies do not share ammunition.
 * In Zombies, the single CZ75 has a 15 round magazine, while Dual Wield CZ75s have 12 round magazines.
 * When Dual Wielded, only the right gun has its slide back if out of ammo.
 * The CZ75 has mostly the same damage and recoil as the USP .45, despite having much less visual recoil. Also, both have the same magazine capacity at 12 rounds (or 18 with Extended Mags).
 * The Dual Wield attachment switch speed is still that of a single CZ75, which is unique among the handguns.
 * The Dual Wielded CZ75s do not sway or move unless the player is sprinting.
 * In Call of the Dead, if the player uses the Zipline while holding Calamity and Jane, the left gun will disappear but can still fire.
 * In some multiplayer stages, the left gun will sound different when firing from the right gun.
 * This is the 3rd highest capacity pistol in Call of Duty, the first being the Five-Seven, the second the M9 and tied for third with the USP.45, but the CZ75 does have the largest pistol magazine on singleplayer though.
 * This is the only pistol with 4 different magazine sizes, 20 in singleplayer, 18 with extended mags, 15 in zombies, and 12 in zombies and multiplayer.
 * When dual wielding, if  the player fires the left CZ75 in a back and forth pattern with the fourth, the left will fire and cause damage but make no sound.
 * In Zombies mode, when moving while prone with Dual Wielded CZ75s, they do not disappear to the bottom of the sceen, as the rest of the guns do.
 * Interestingly, the CZ75 makes its first appearance in the game in Numbers, which takes place in the beginning of 1968, but the real-life CZ75 wasn't developed until seven years later, in 1975.
