Pack-a-Punch Walkthrough in MW3 Zombies

In Call of Duty Zombies, one of the most important tools is the Pack-a-Punch machine. This machine upgrades your weapon, doubling its damage and magazine size. Some weapons even get special effects, like pistols shooting explosive rounds.

MW3's Zombies and the Pack-a-Punch 

Modern Warfare 3 introduces a massive Zombies map, making it tricky to find the Pack-a-Punch machine. But once you're used to the map and have managed a few successful escapes (exfils), locating and using these machines becomes much easier. You can even start a mission with an upgraded weapon.

Finding and Using Pack-a-Punch Machines

• No special steps are needed to unlock Pack-a-Punch machines; just find them using the tac-map.
• They're scattered throughout Urzikstan, with more in lower-threat areas and fewer in higher-threat areas.

• Use vehicles, jump portals, and drones to reach them quickly.
• Learn their few spawn locations to plan your route in each mission.

• The upgrade level depends on the machine's threat area: Level I in Tier I, Level II in Tier II, and Level III in Tier III.
• Make sure you have enough essence (15,000 for Level III) and perks like Jugger-Nog to survive.

Upgrading Without Pack-a-Punch Machines

• Find aetherium crystals in loot crates, around the map, or from completing contracts.
• Completing contracts boosts your chance of finding these crystals.
• Use crystals to upgrade weapons without needing a Pack-a-Punch machine.
• You can also find Aether Tools that upgrade the rarity of your weapon.

Starting with an Upgraded Weapon

• Collect aetherium crystals, an Acquisition item, during your missions.
• Choose to store Raw, Refined, or Flawless Aetherium Crystals to upgrade weapons up to Level III in future games.
• Successfully exfil to keep stored crystals.
• Store up to ten acquisitions for future use.
• Advance in story missions to craft crystals and start games with an upgraded weapon.

And that's your complete guide to mastering the Pack-a-Punch in Call of Duty Modern Warfare 3 Zombies. With these tips, you'll find upgrading your weapons and tackling those zombies much more manageable. Remember, knowing the map and effectively using aetherium crystals can give you a significant advantage right from the start of a mission. Keep exploring, completing those contracts, and you'll be a Pack-a-Punch pro in no time. Happy zombie klling in MW3!
