As we progress into 2026, the enduring challenge of Modern Warfare 3's Zombies mode continues to captivate players. Reaching the Tier 5 objectives in Act 1 is a significant milestone, signaling that the most grueling grinds are behind you. The path forward, starting with the 'Hands Off' objective, is designed to be more straightforward, though it demands strategic execution. This mission tasks you with eliminating both Zombies and Mercenaries using a Sentry Gun, a powerful but sometimes elusive piece of gear. I've found that with the right approach, this entire objective can be completed efficiently in a single deployment, turning a potentially tedious task into an exhilarating display of automated firepower.
🔫 How To Acquire a Sentry Gun
The primary hurdle for many is obtaining the Sentry Gun itself. While there's a chance to loot one from Mercenary Stronghold safes or Aether Caches, relying on random drops can be frustrating and time-consuming. The most reliable and efficient method is to purchase it directly from a Buy Station. However, not every station carries this equipment. You must seek out those located within Medium-Threat or High-Threat zones. The good news? It's surprisingly affordable at just 2,000 Essence. This low cost means you can quickly earn the necessary funds by completing just one or two contracts in the safer, Low-Threat zone at the start of your match. Securing your Sentry Gun early gives you the entire session to focus on the elimination requirements.
🧟 Mastering Zombie Eliminations
For the segment requiring 20 zombie kills, placement is everything. The Sentry Gun excels in areas with concentrated, predictable undead traffic. I recommend two prime locations:
-
Extraction Zones: Once you call the extraction helicopter, a sizeable horde converges on the location. Deploying your Sentry Gun here allows it to mow down waves of zombies effortlessly as you defend the landing zone.
-
Infested Strongholds: These locations are naturally teeming with the undead. Setting up your turret at the entrance or a key chokepoint as you clear the stronghold guarantees a rapid accumulation of kills.
Both strategies leverage the game's spawn mechanics, ensuring your automated ally gets the job done quickly without you needing to lure enemies manually.
💀 Tackling Mercenary Kills
The requirement for 10 Mercenary kills presents a different challenge. Human adversaries are more tactical and can quickly destroy your Sentry Gun if left unprotected. You have two main avenues for success:
-
Indoor Deployment in Strongholds: Raid a Mercenary Stronghold and place the Sentry Gun inside a room or corridor. This confines the mercenaries and can lead to quick, chaotic eliminations as they round corners into its line of fire.
-
Perimeter Assault on Camps: Set up the turret on the outskirts of a Mercenary Camp. Use it as suppressive fire while you flank or draw enemies out. Be prepared to defend the turret, as focused fire from multiple mercenaries can dismantle it rapidly.
⚠️ Pro Tip: It's wise to plan for two separate engagements at Camps or Strongholds. Rarely will a single Sentry Gun survive long enough to secure all 10 kills in one assault unless you are meticulously drawing aggro and providing cover fire.
🏆 Completion and Rewards
Upon successfully meeting both kill conditions, the objective is marked complete. Your reward is the final Cyphered Tablet, a key story item that concludes this chapter of the Act 1 narrative. This achievement not only advances the plot but also solidifies your mastery over utilizing support streaks in high-pressure undead and mercenary combat scenarios.
| Objective Component | Target | Recommended Strategy |
|---|---|---|
| Zombie Kills | 20 | Deploy at Extraction Zones or Infested Strongholds. |
| Mercenary Kills | 10 | Use indoors in Strongholds or on the perimeter of Camps. |
| Sentry Gun Source | 1 Unit | Purchase for 2,000 Essence at Medium/High-Threat Buy Stations. |
In summary, the 'Hands Off' objective is a test of resourcefulness and tactical placement. By securing your Sentry Gun through purchase, and strategically deploying it in high-traffic zombie areas and against mercenary positions, you can efficiently conquer this Tier 5 challenge. It's a satisfying demonstration of letting machinery do the dirty work, paving a smooth path toward completing the rest of Act 1's demanding objectives. Remember, in the ever-evolving landscape of Modern Warfare 3 Zombies, efficiency and smart planning are your greatest weapons.
