Pack-a-Punch Secret Weapons Guide

Overview

Pack-a-Punch (PAP) in Astra Malorum reveals secret abilities and transformations for all weapons. Some weapons get unique pack-a-punch names and special mechanics that dramatically change how they perform.

Top Secret Pack-a-Punch Weapons

🔫 1. Jerry Pistol (Transformation) ▼
Upgraded from standard pistol:
  • Completely transforms into a fully automatic weapon
  • No need to ADS (aim down sights)
  • Can be dual-wielded for massive damage output
  • ✅ Best for: Speedrunning and training zombies
💣 2. Ballist Artillery (Mortar Upgrade) ▼
Upgraded from Mortar Launcher:
  • Becomes a full artillery/mortar launcher
  • Massive AoE damage with trajectory compensation
  • Added ADS zoom for precision aiming
  • ⚠️ Warning: Friendly fire can damage you with the blast
⚡ 3. Spartan Laser Beam ▼
Charged Energy Weapon:
  • Continuously fires without reloading after PAP
  • Shoots 24 rounds in a beam sequence
  • Insane damage output for high-round play
  • ⏱️ Note: Slow fire rate but devastating impact

Hidden Weapon Transformations

Base Weapon PAP Name Special Ability
Ray Gun Mark 2 Porter's Mark 2 Classic 3-round burst (buffed damage)
XR3 Ion Pandemonium OG Chain lightning effect on crits
Warden Sniper ET2 Brutus Mob of the Dead reference (huge armor dmg)
VSera Sniper Reconfigurator Double ammo + tight hipfire spread
Jagger Pistol Jagger SMG Transforms pistol into rapid-fire SMG

Glitches & Exploits (Use with Caution)

⚠️ Note: These exploits may be patched in future updates. Check patch notes before attempting.
1. Pack-a-Punch Ammo Duplication
Stack ammo crates in specific locations, then PAP certain weapons to overflow ammo reserves past maximum cap.
2. Weapon Clipping Glitch
Use certain PAP weapons (like Ballist Artillery) to clip through map geometry in Stargazer's Courtyard, allowing access to unintended safe spots.
3. Frenzy Guard Stacking
Combine PAP with Frenzy Guard + Frenzy Fire augment. This stacks damage multipliers exponentially, making even basic weapons one-shot kills on high rounds.

Tier 4 Pack-a-Punch (Cursed Mode)

🏆 Ultimate Upgrade: Collect all 6 Relics (3 Tier 1, 2 Tier 2, 1 Tier 3) and spend 100,000 points at Pack-a-Punch to unlock Cursed Mode.
  • Exclusive ultra-rare camo unlocked
  • Maximum weapon damage boost (beyond Tier 3)
  • Unique visual effects and animations
  • Guaranteed better performance in high rounds (50+)

Efficiency Tips & Tricks

  • New Trick: Fail the sun trap 4/5 times to force spawn Oscar immediately
Saves 3-5 minutes
