The Black Ops 7 Zombies beta introduces players to 16 weapons, each featuring unique Pack-a-Punch upgrades that increase their effectiveness against endless waves of undead. This guide covers all available weapons in the beta, analyzing their Pack-a-Punch abilities, damage output, and overall utility to help players choose the best options for surviving high rounds.

Shotguns
· Echo 12 → Deja Boom
Upgraded with double ammo capacity and a haunting sound effect. Damage output is average, but attachments improve its utility.

· M10 Breacher → X10 SIT Fracture
Gains a wider hipfire spread, faster fire rate, and a charge shot option. However, the charge shot does not increase damage.

Launchers
· Ark M1 Launcher → Arimedes Insight
A top-tier weapon after upgrading, holding 24 rockets in a limitless clip. Combines launcher power with sniper-like precision, excelling at massive crowd control and high-round survivability.

Assault Rifles & Marksman Rifles
· M8A1 → Macro Airator
Keeps its four-round burst mode with no special upgrade effects, but remains a solid mid-damage option.

· VS Recon → Visera Reconfigurator
A bolt-action sniper that gains a laser sight and tighter crosshair for hipfire accuracy. Strong choice for long-range encounters.

· XR3 Ion Sniper → Pandemonium OG
Fires triple energy projectiles but loses some ammo capacity when upgraded. No unique effects but benefits from attachments and double tap perks.

Submachine Guns (SMGs)
· Dravk 45 → Upeyar 189
Fast, accurate, and efficient with a large ammo pool. Strong for sustained firefights.

· Razer 9mm → Haniwa’s Frenzy
Features a tighter crosshair and faster fire rate. Reliable and effective for close-range combat.

· Peacekeeper → UT’s Petition
Returning fan-favorite from Black Ops 2. While lacking special effects, its high fire rate and strong damage make it ideal for points and clearing hordes.

· Ryden 45K → Cibil’s Sentence
Becomes more deadly with full auto capability and higher fire rate, though without unique Pack-a-Punch traits.

Pistols
· Jäger 45 → Jerry
Transforms into a shotgun-style pistol with larger crosshair and tighter spread. Extremely powerful when dual wielded.

· KOD 9 → No Cap
A fully automatic pistol that doubles ammo capacity after upgrading. Deadly in akimbo form and highly effective as a secondary.

Light Machine Guns (LMGs)
· Mark 78 → Meteoric Calamity
Equipped with a 100-round magazine and minimal recoil when Pack-a-Punched. Excellent for mobility and sustained firepower.

Melee Weapons
· Flatline M2 → Picker Shock
Deals high melee damage but with slower swing speed. Offers no unique upgrade abilities but viable in close-quarters combat.

Wonder Weapons
· Ray Gun M2 → Porter’s X2
The iconic weapon remains powerful up to round 42, after which its strength drops slightly. Still a strong mid-game option.

· Ray Gun Mk2 → Porter’s Mk2 Ray Gun
Another fan-favorite, featuring high damage output and unique camos. Effective up to the mid-40 rounds.

Gameplay Notes
Most weapons retain their original mechanics but gain increased ammo capacity and unique enhancements after upgrading. Synergy with fire rate mods, extended magazines, and double tap perks makes them significantly more effective in later rounds.

Future Expectations
The beta currently features 16 weapons with Pack-a-Punch upgrades. The full release in November is expected to expand the arsenal with additional weapons, attachments, and possibly more unique upgrade effects. Many communities recommend sticking to legit and cheap CoD BO7 Bot Lobby options to avoid risks.

The Ark M1 Launcher, select SMGs like the Dravk 45 and Razer 9mm, and timeless favorites such as the Ray Gun and Peacekeeper stand out as top performers in the Black Ops 7 Zombies beta. The upgraded shotgun pistol provides an interesting twist, while LMGs prove excellent for sustained firepower. Players should experiment with different builds to maximize synergy and prepare for the expanded arsenal in the full release.
