Black Ops 7 Zombies launches with more than 30 weapons, each gaining increased power and, in some cases, unique traits when upgraded through the Pack-A-Punch (PaP) machine. The following guide compiles every PaP weapon at launch, organized by class, with corrected weapon names, clear descriptions, and simplified explanations of their behaviors and strengths.

Assault Rifles
1. M15 Mod Zero → Nyxfall
Unlocked by default, the upgraded Nyxfall offers double the magazine size, a strong damage boost, and a significantly faster reload—about 1.5× faster even without Speed Cola. This makes it a solid early-game rifle.

2. AK-27 → Impossible Oyster X
Unlocked at Level 4, this rifle references Black Ops 3’s “Impossible” Easter Egg. With 45 rounds per mag and 635 in reserve when upgraded, it resembles the classic KN-44 in performance—an above-average, reliable rifle.

3. MXR-17 → Battlement Aside
Unlocked at Level 16, the MXR-17 is a semi-auto rifle that lacks impact even after upgrading. The PaP version increases ammo capacity but adds no notable fire-rate or performance improvements.

4. X9 Maverick → Hang-X
Unlocked at Level 28, this burst-fire rifle gains 60 rounds per mag and 780 in reserve when PaP’d. Aside from the increased ammo and damage, the upgrade offers no unique traits.

5. DS-20 Mirage → Duality of Blam
Unlocked at Level 37, this slow-firing full-auto AR receives a small RPM boost and increased ammo after PaP, but remains underwhelming compared to other rifles.

6. Peacekeeper Mk1 → Uthus Petition
A legendary return of the Black Ops 2 Peacekeeper. With a high fire rate, 60-round mag, and 780 reserve when PaP’d, it stands out as one of the strongest ARs available and can be purchased from certain Wall Buys. Those who want controlled testing conditions often choose a CoD BO7 bot lobby, a feature many cheap and legit practice services let you buy safely.

Submachine Guns (SMGs)
7. Ryden 45K → Sibyl Sentence
Fast-firing and available from the start, this SMG becomes highly effective up close when PaP’d, gaining a doubled ammo pool and consistent damage output.

8. RK-9 → Contagion Conductor
A three-round-burst SMG that rewards accurate headshots. PaP improves the fire rate slightly and doubles its ammo to 80 rounds per mag.

9. Razor 9mm → Tanny Frenzy
A fully automatic SMG with 60-round mags after PaP. The key upgrade benefit is an extremely tight hip-fire spread, making ADS unnecessary in most situations.

10. Dravk 45 → UPYR-1819
Unlocked at Level 34, this SMG has fast RPM but no special PaP traits. It remains a dependable, straightforward SMG.

11. Carbon 57 (PDW) → LC-Carbon
Unlocked at Level 46, this PDW-style SMG gains a massive 90-round mag and 720-round reserve after PaP. Though lacking unique traits, it is one of the best high-ammo SMGs.

12. MPC-25 (MSMC) → MAL Practitioner 25,500
Unlocked at Level 55, this fan-favorite SMG offers strong damage and a 45-round mag when PaP’d. No special ability is added, but performance remains excellent.

Shotguns
13. M10 Breacher → X10 Silt Fracture
Unlocked from the start, this slow-firing shotgun gains a 14-round mag and faster reload speeds once upgraded.

14. Echo-12 → Dayjar Boom
Unlocked at Level 22 and available on the Van Dorn Farm wall. PaP doubles its mag to 24 and greatly tightens hip-fire spread—especially in Tactical Stance—making it one of the top shotgun options.

15. Akita → Hatchet Echo
Unlocked at Level 40, this extremely fast-firing shotgun becomes devastating when upgraded, featuring 42 rounds per mag. With proper attachments, it rivals the Maelstrom from Black Ops 6 and is among the strongest weapons in the game.

Light Machine Guns (LMGs)
16. Mark 78 → Meteoric Calamity
Unlocked immediately and previously overpowered in the beta. In the final game, it behaves like a standard LMG after PaP, increasing ammo but losing its earlier unique mobility bonus.

17. XM325 → Epilates
Unlocked at Level 31, this hybrid AR-LMG performs better than the Mark 78, offering a high fire rate and a 120-round mag once PaP’d. No special abilities are added.

Marksman Rifles
18. M8A1 → (PaP Name Unconfirmed)
Unlocked at Level 10 and returning from Black Ops 2, the M8A1 doubles its ammo when PaP’d and delivers strong burst-fire damage, despite lacking special traits.

19. Warden → ET2 Brutus
A slow but hard-hitting rifle. Upgraded, it gains more ammo but remains weaker than other rifles in its class.

20. M34 Nova Line → Desecrated Duelist
Unlocked at Level 49 and similar to an M1 Garand. Its PaP version gains a very fast fire rate, making it one of the most competitive marksman rifles available.

Sniper Rifles
21. VS Recon → VSERA Reconfigurator
A classic high-damage sniper. When upgraded, it gains tight hip-fire accuracy and doubled ammo, making it effective even without a scope.

22. Shadow SK → Merk Skogsra
Unlocked at Level 13, this semi-auto sniper gains a large 22-round mag, increased fire rate, and excellent hip-fire accuracy when PaP’d—one of the best snipers overall.

23. XR-3 Ion → Pandemonium OG
A three-round-burst sniper with extremely high damage. Though it gains no special PaP abilities, it has some of the highest DPS potential in Black Ops 7 Zombies.

Pistols
24. Jagger 45 → Gerry Pistol
The starting pistol becomes a shotgun-style sidearm when upgraded, with a wide hip-fire crosshair. Dual-wielding it results in surprising mid-round viability.

25. KOD-9 (CAP-40) → No Cap
A fast full-auto pistol that becomes even more lethal when PaP’d. Extended mags and akimbo attachments make it a powerful secondary weapon.

26. Velox 5.7 → Ruin
A burst-fire pistol with a doubled mag and slightly faster reload when PaP’d. Offers solid performance but no unique traits.

Launchers
27. Aero-109 → Ballist Artillery
A slow but extremely powerful launcher that fires a mortar-style projectile when PaP’d. Its heavy zoom and ballistic arc make it difficult but potentially devastating.

28. ARK-M1 → Archimedes Insight
A charge-beam launcher that becomes dramatically stronger when PaP’d. It gains a 24-shot magazine that fires continuously without reloading—similar to a Spartan Laser.

Melee Weapons
29. Knife → Pointed Remark
The standard knife gains improved melee potential when upgraded. With Melee Macchiato, it becomes a fast and effective close-quarters option.

30. Flatline Mk2 → Ticker Shock
Unlocked at Level 49, but its PaP version does not noticeably increase melee speed, making the knife the superior choice.

Wonder Weapons
31. Ray Gun → Porter’s X2 Ray Gun
A classic upgrade: doubled ammo, increased damage, and improved performance when paired with Double Tap and Elemental Pop.

32. Ray Gun Mark II → Porter’s Mark II Ray Gun
One of the highest-damage weapons in the game. Ammo can run out quickly but remains excellent for boss fights and high-round survival.

33. Necroluid Gauntlet
A unique Wonder Weapon with its own mechanics and powers, serving as the final addition to the launch arsenal.

Black Ops 7 Zombies offers a diverse arsenal of weapons, each gaining significant power and expanded ammo reserves through Pack-A-Punch. While most upgrades focus on raw damage and magazine size, several standouts—such as the Akita shotgun, Shadow SK sniper, XR-3 Ion, and Jagger 45 pistol—gain dramatic improvements that meaningfully change gameplay. Whether experimenting with classics like the Ray Gun or pushing into late rounds with high-DPS rifles, players have a wide range of effective tools at launch.
