How to Upgrade the CASTER Turret in Reckoning
Upgrading the CASTER Turret is a multi-step process that requires persistence and strategy. Here’s how it works:
1. Purchase the CASTER Turret 5 Times
- First, buy the turret five times from its designated location.
- After the fifth purchase, the Janus P.A. System will announce:"Error: Memory full. Upgrade capacity to continue learning."
- This means the turret is ready for its first upgrade.
2. Collect a Hard Drive from Zombies
- Kill zombies until one drops a Hard Drive (identifiable by its golden glow).
- Once obtained, head to the T1 Quantum Computing Core.
3. Insert the Hard Drive at Project Janus
- Inside the T1 Quantum Computing Core, locate the Project Janus terminal (southeast side of the central terminal).
- Interact with it to insert the Hard Drive, triggering a mini-lockdown.
4. Survive the Lockdown (or Skip It)
- Defend the terminal from zombies until the upgrade completes.
- Pro Tip: Start the upgrade at the end of a round for an easier defense.
- Alternative Method: Some players report that fast-traveling away immediately after inserting the Hard Drive skips the lockdown entirely.
5. Repeat for Upgrades 2.0, 3.0, and 4.0
- For Upgrade 2.0, purchase the turret 10 more times (15 total).
- For Upgrade 3.0, purchase it 15 additional times (30 total).
- For the final Upgrade 4.0, purchase it 15 more times (45 total).
- Each upgrade requires a new Hard Drive and lockdown defense.
All CASTER Turret Upgrades & Effects
| Upgrade Tier | Effect |
|---|---|
| 1.0 (Base) | Standard turret with high damage output. |
| 2.0 | Players become immune to CASTER Turret damage. |
| 3.0 | Increased power + large splash damage radius. |
| 4.0 (Max) | Faster fire rate, stronger shots, and a chance to apply Brainrot Ammo Mod effect. |
Each upgrade makes the turret more lethal, essential for surviving high-round zombie waves.
Best Strategies for CASTER Turret Upgrades
✅ Farm Kills Efficiently – Let the turret rack up kills to trigger Hard Drive drops faster.
✅ Upgrade Between Rounds – Avoid starting lockdowns mid-round to prevent being overwhelmed.
✅ Use Fast Travel Skip (If Patched, Be Prepared to Defend) – Some players bypass the lockdown by fast-traveling immediately.
✅ Prioritize Upgrades in Co-op – Teammates can help defend the terminal during lockdowns.
Final Thoughts
The CASTER Turret is a game-changing asset in Black Ops 6 Zombies Reckoning, especially when fully upgraded. While the process is grindy, the payoff—massive damage, splash radius, and Brainrot effects—makes it worth the effort.
