Rezi 12 at a glance

Rezi 12 is one of Activision’s 2 launch shotgun entries. The official roster contains 33 weapons: 24 Primary Weapons, eight Secondary Weapons and one Melee Weapon. That total excludes Tactical and Lethal equipment, older cosmetic labels and duplicate Blueprint variants. This record uses the October 19 launch article, checked October 26, rather than treating earlier Beta cards as the current specification. Rezi is the semi-automatic 12-gauge shotgun. Enforcer changes the cycling to pump action and adds explosive slugs on a side-saddle. The listed base cyclic rate describes Rezi before that action change, rather than establishing the firing cadence of the conversion.

In-game description

A fast-cycling semi-auto 12-guage, the modular Rezi 12 delivers powerful, controlled shots with smooth recovery. Built for decisive close-range work.

The publisher’s description above explains the intended role of Rezi 12. It should be read alongside its own numeric block: 60 weapon levels, 6 base rounds, 24 reserve rounds and 150 RPM. These are published fields, not measurements made by this wiki. Descriptive terms about power, stability or speed do not establish a damage table, a time-to-kill result or a tested advantage against a particular opponent. The configuration and mode still matter when interpreting such claims.

How it fits the class

Warlord provides a same-class reference: its launch block lists 14 rounds, 42 in reserve and 105 RPM. Rezi 12 lists 6 rounds and 24 in reserve. Compare these base configurations before adding an Apex or a capacity attachment. A larger ammunition count describes ammunition available before replenishment; it does not establish more kills, a faster reload or better handling. Other class members are linked below so this comparison remains part of the complete roster.

Ammo and supply

The official launch reserve for Rezi 12 is 24 rounds, separate from the 6 loaded rounds. Reserve is ammunition outside the current magazine or feed, not a magazine attachment to add to its capacity. This entry does not infer a pickup amount, resupply interval or shared ammunition pool from a cartridge name. In DMZ, access and replenishment depend on the deployment and FOB systems; the article’s launch reserve field does not locate a specific ammunition cache or promise the same inventory after looting.

Magazine options

The launch block supplies 6 base rounds for Rezi 12. Its attachment categories are listed separately below, and the article does not enumerate every magazine capacity or reload duration. Do not add a chambered round to the published figure or import an extended magazine from an older game. Any Apex description that explicitly changes the feed or capacity describes a different configured weapon. Keep the original base count visible so a later build comparison can distinguish the source specification from the selected attachment setup.

Gunsmith attachment slots

The published categories for Rezi 12 are Optic, Bolt, Muzzle, Guard, Barrel, Underbarrel, Rear Grip, Comb, Stock, Laser, Ammunition. Its Apex is Rezi 12 Enforcer. Enables pump-action cycling and is outfitted with a side-saddle for hot-loaded explosive slugs. The added capability extends the platform’s engagement envelope well beyond tradition 12-gauge roles. Apex Attachments are equipped separately and do not consume an ordinary attachment slot, but the source may explicitly block individual categories for a conversion. Read those restrictions before planning a combination. Weapon progression unlocks shared attachments for compatible weapons, while Weapon Prestige relocks attachments on the weapon being Prestiged. The Gunsmith reference explains that progression context.

What is not measured yet

Infinity Ward states that Multiplayer and DMZ have bespoke tuning. Record the mode, patch date and exact configuration when measuring damage, recoil, effective range or time to kill; published cyclic rate alone cannot supply those results. The October 23-25 patch notes distinguish implemented fixes from proposed future tuning.

How to unlock it

Rezi 12’s Main Player Levels unlock table lists Player Level 4. Its individual Available Criteria entry agrees: Unlocked at Player Level 4. This is a player progression requirement, distinct from the 60 weapon levels listed for attachment progression and access to Weapon Prestige. Create-a-Class opens at Player Level 4. In DMZ, unlocked weapons can be purchased through the FOB Gunsmith with sufficient DMZ Cash; looting, Weapon Manuals and the FOB Vendor provide other acquisition routes described by Activision. A cosmetic Blueprint name is a separate entitlement, rather than a replacement for these base progression rules.
