The 5-Step Master Guide To GS45 Hipfire Kills In Zombies (How To Beat The Pack-a-Punch Bug)
The GS45 Pistol hipfire kills challenge is one of the most infamously frustrating steps in the Black Ops 6 Zombies camo grind, and as of December 2025, it remains a major hurdle for players seeking Pistol Mastery. This challenge, which requires 300 hipfire kills to unlock the coveted Siamese camo, is plagued by a long-standing bug: the kills simply do not track if you upgrade the weapon using the Pack-a-Punch machine. This means you must complete this high-volume task with the base-damage version of the pistol, forcing a completely different strategy than the typical high-round PaP approach.
This definitive guide provides the absolute best, up-to-date GS45 hipfire loadout and a proven 5-step farming strategy to bypass the dreaded Pack-a-Punch bug and secure your 300 hipfire eliminations as quickly as possible. Forget about high rounds; the key to success lies in optimizing for low-round efficiency and maximum hipfire accuracy to make this tedious challenge a breeze.
The Definitive GS45 Hipfire Loadout for Low-Round Zombies Farming
The core of this strategy is to maximize the GS45’s hipfire accuracy and damage output in the early rounds (Rounds 1–5) where the base pistol can still one-shot or two-shot the standard zombies. Since you absolutely cannot Pack-a-Punch the weapon for this challenge, every attachment must be geared toward tightening the hipfire spread and increasing your kill speed.
- Muzzle: Suppressor (or a Barrel for Damage). While a suppressor is great for stealth, for pure hipfire grinding, consider a barrel that boosts damage range or bullet velocity to ensure one-shot kills last through Round 4.
- Barrel: Long Barrel (e.g., 6.5" Long Barrel). A longer barrel is crucial for extending the one-shot kill potential of the base GS45 to slightly higher rounds. This is a non-negotiable attachment for low-damage weapons.
- Laser: Hipshot L20 Laser. This is the single most important attachment. It drastically reduces the hipfire spread, making your shots far more reliable without needing to aim down sights (ADS). Prioritize any laser that specifically improves hipfire accuracy.
- Magazine: Extended Magazine (e.g., 20 Round Mag). The base magazine size is too small for managing even a small train of zombies. The extended mag minimizes reloads and maximizes your time spent firing, which is essential for a high-volume kill challenge.
- Stock/Rear Grip: No Stock / Stippled Grip Tape. Use the remaining slot to further boost either movement speed (No Stock) or hipfire recoil control/accuracy (Stippled Grip Tape). For hipfire, a grip tape is often the better choice for tighter groupings.
Loadout Summary: The goal is to create a "laser beam" from the hip. The combination of the Hipshot Laser and an Extended Magazine will carry the bulk of the work, allowing you to quickly mow down the weaker, low-round zombies.
The 5-Step Hipfire Farming Strategy (No PaP Allowed)
The moment you Pack-a-Punch the GS45, the kill tracker for the Siamese camo challenge will likely freeze, making all your subsequent hipfire eliminations worthless. Therefore, the strategy must focus on high-density, low-health zombie farming.
1. Choose the Right Map and Mode
For the fastest results, you need a map with high zombie density and easy access to a fast-spawning area. The best option is often the introductory map in the current Black Ops 6 Zombies rotation, specifically playing on the Solo difficulty setting. Solo mode ensures the zombie health scales to its absolute minimum, allowing the un-PaP’d GS45 to remain effective for longer.
- Target Rounds: Rounds 1 through 5.
- Optimal Area: A small, contained starting area with only one or two barriers to open. This keeps the zombies localized and easy to manage.
2. Maximize Early-Round Efficiency
Start the game and immediately begin shooting from the hip. Do not ADS at all. Use your starting points to purchase the Extended Magazine for the GS45 first, as this will immediately boost your efficiency. Focus on shooting zombies in the chest or upper body—precision is not as important as volume when hip-firing.
- Tip: Run a circular route (training) in the starting area, and when you have a small group, turn and spray from the hip. The tight spread from your loadout will ensure multiple hits.
3. Use Equipment and Field Upgrades Strategically
Since the GS45’s damage is low, you can't rely on it alone to clear large groups. Use your equipment to soften or finish off the horde.
- Lethal: Use Molotov Cocktails or Frag Grenades to weaken a train of zombies. Once they are damaged, switch to the GS45 and hip-fire to secure the final kill. The kill credit goes to the weapon if it delivers the final blow.
- Field Upgrade: Use an upgrade like Frost Blast or Energy Mine to slow or damage a crowd, then finish them off with the pistol. This is crucial for maintaining control and getting high-volume kills quickly.
4. The Round 5 Exfil Loop
Once you hit Round 5 or 6, the GS45 will start to struggle, requiring too many shots to kill a single zombie. This is when the grind slows down dramatically. To maintain the fastest possible pace, your best option is to Exfil (Extract) at the end of Round 5 or 6.
- Why Exfil? Exfiling saves your progress and allows you to immediately start a new match. Restarting at Round 1 is far more efficient than spending 10 minutes shooting a single zombie 15 times with an un-PaP’d pistol in Round 7.
- The Loop: Play Rounds 1-5, Exfil, and repeat. This is the fastest method to accumulate 300 kills while the GS45 remains a one-to-two-shot kill weapon.
5. Monitor the Challenge Tracker
Always check the Siamese camo challenge tracker in the pause menu between rounds to ensure your hipfire kills are actually counting. If the tracker is not moving, restart the game, as a client-side bug may have occurred. Never assume the kills are tracking, especially before attempting the challenge.
Why the GS45 Hipfire Kills Challenge is So Difficult
The difficulty of the GS45 hipfire challenge stems from the combination of its low base damage and the critical Pack-a-Punch bug. The GS45 is a Pistol-class weapon, meaning it has one of the lowest damage profiles in the game. In Zombies, weapon damage quickly falls off as the rounds progress and zombie health exponentially increases.
Normally, players would overcome this by using the Pack-a-Punch machine to upgrade the weapon, often turning it into the Mustang and Sally explosive variant, which is ideal for clearing hordes. However, multiple community reports and tests confirm that once the pistol is PaP'd, the Siamese camo challenge tracker breaks and stops recording hipfire kills.
This forces players to rely on the base weapon, which means the 300 kills must be farmed in the initial few rounds. This is a deliberate, slow, and repetitive process, but following the early-round Exfil loop strategy is the only reliable way to overcome this frustrating glitch and complete the Pistol Mastery grind. Focus on hipfire accuracy, extended magazines, and low-round resets to get your Siamese camo unlocked.
