Delta Force second-anniversary season adds plenty of reasons to return to Operations, and Zola’s Harmonica is one of the more interesting hidden rewards to chase. The current Reorientation season runs from September 8 through November 9, with the anniversary event offering activity missions and milestone rewards.
The Harmonica quest is much easier when you understand one important rule: secure important quest items as soon as you obtain them. That way, dying doesn't necessarily mean starting the entire chain again. If you want to reduce the resource pressure during repeated runs, MMOexp can also help you prepare additional Delta Force Tekniq Alloy so you can focus more on the quest itself.
Start With Zola and Secure Every Key Item
Head to the required location, find Zola, and begin the quest chain.
Your first objective involves taking down Rice and collecting his helmet. Don't carry it around longer than necessary. Put the helmet into your Safe Box immediately, then return to Zola and hand it in.
The next task sends you into the crocodile cave. Clear the crocodiles, collect the soldier's armor, and submit it to Zola.
The early stages are straightforward, but the Safe Box is what makes this quest much more forgiving.
Weapon Parts and the Daily Reset
The next stage requires waiting for the mission refresh at 2:00 UTC.
Once the objective becomes available, travel to the designated locations in Longbow Valley and collect the required weapon components. You don't have to find everything in one raid. Split the objectives across multiple runs if necessary, and secure valuable components whenever possible.
After turning in the parts, Zola provides funds for the next objective. You'll need to purchase four types of supplies and bring them to the required location in a later run.
After that, continue to the designated area and collect the chest rig. Once again, secure it immediately.
This is where smart inventory management matters most. If you're trying to speed up preparation, buy Delta Force Tekniq Alloy through MMOexp can help reduce some of the resource farming between runs.
The Underwater Backpack Is the Dangerous Part
After another 2:00 UTC reset, the underwater stage becomes available.
Before entering the water, upgrade the Diving Center to at least Level 2, with Level 3 being even more comfortable, and bring Tempest for the dive.
At the underwater entrance, follow the route by going right first, then left and deeper into the cave. When you reach the marked rock area, use Tempest's ultimate ability and continue downward.
Once you see the objective marker, grab the backpack.
Don't fight unnecessarily on the way out. Remember your route before entering, follow the light back toward the surface, and get to safety as quickly as possible. Unlike some earlier objectives, losing the backpack can force you to repeat the underwater section.
Finish the Final Combat Mission
After handing in the backpack, accept Zola's final mission.
Follow Sara's guards toward the Train Station and eliminate the Havoc forces. Then move toward the WSR Laboratory and clear the enemies there.
The final objective takes you to the Radar Station, where you need to bring down the arriving helicopter.
Once the mission is complete, return to Zola.
Your Harmonica will be delivered through in-game mail, completing the Easter egg chain.
What If You Die?
Don't panic if a run goes wrong.
The key is to understand which items you've already secured. Most stages don't require you to replay the entire quest from the beginning, and the final mission can be picked up from Zola again if you fail.
The safest strategy is therefore simple: secure quest items, extract early, and never turn a successful objective into a greedy extra run.
Final Takeaway
Zola's Harmonica quest is less about winning every raid and more about controlling your risk. Complete the stages in order, respect the 2:00 UTC refresh, use the Safe Box whenever possible, and treat the underwater backpack as the biggest extraction priority.
Once the final helicopter is down, return to Zola and check your mail—the Harmonica is your reward.
