If you thought Delta Force was all about extraction, firefights, and getting out with your loot, Longbow Valley has a very different surprise waiting for you. The hidden Loyalty Grove 2.0 questline lets you earn a unique interactive collectible—a playable Harmonica. The entire chain has six stages, but you’ll need roughly three days to finish it because several steps require you to extract and return the following day.
The most important rule is simple: complete every stage in order, turn it in, extract, and wait for the next day whenever required.
Stage 1: Find Ree’s Helmet
Head into the old Bird Nest quest cave and speak with Zolazar at the end. She’ll send you after Ree and ask you to recover the helmet.
Ree has a relatively low spawn rate, so don’t expect to find the target every raid. Only players who have accepted the quest can see the relevant drop. A Recon Operator is useful here because Radar Stations, Power Stations, the Hotel, and Blue Pier can help you scout for the required activity.
Once you have the helmet, return it to Zolazar and extract from the match. That extraction is required before the next stage becomes available.
If you want to spend less time farming basic resources and more time completing the quest, you can buy Delta Force Tekniq Alloy through MMOexp to speed up your overall progression.
Stage 2: Raid the Crocodile Nest
Come back the next day and Zolazar will send you into the same cave to recover an armor piece from the crocodile nest.
The area can be crowded with enemies, but the objective itself is straightforward. Clear enough space to search safely, grab the armor, return it to Zolazar, and extract again.
Don’t try to rush into Stage 3 during the same deployment—the quest progression is designed around the daily reset.
Stage 3: Collect the AKM Parts
This is where the quest starts sending you across Longbow Valley.
You need to search four locations:
Near the Church
On top of the tank outside the Hotel
The parkour area in Amina Village
Near the minefield beside the waterfall
The good news is that these components can be stored in your Secure Safe Box, making this stage much less punishing if you’re worried about losing progress.
You can complete the locations across multiple raids instead of forcing everything into one run. For players who want to reduce unnecessary deaths and resource costs, having extra Delta Force Items available through MMOexp can also make the grind easier to manage.
Stage 4: Trade Supplies for the Chest Rig
Zolazar will provide 30,000 Technic Alloys, which you’ll use to obtain four required supplies:
Purified Water, Canned Food, Medical Alcohol, and Basic Fuel.
Take all four items to the iron gate at Amina Village and submit them. Then extract.
On your next deployment, return to Amina Village and collect the chest rig beneath the tower. Like the AKM parts, this item can be placed inside your Secure Safe Box, so don’t leave it sitting in your normal inventory.
Stage 5: Dive Into the Deep Cave
This is easily one of the most dangerous stages.
You need to bring Tempest, while the Diving Center must be at least Level 2. Stamina consumables and a weapon with a flashlight are highly recommended.
Enter the underwater cave, turn right, then left until you reach the marked rock. Use the rope and continue deeper into the cave to find the backpack.
Unlike some previous quest items, the backpack cannot be stored in your Secure Safe Box. Once you have it, extraction becomes the priority. Don’t get greedy and throw away the entire quest chain for one extra loot room.
Stage 6: Clear Havoc and Claim the Harmonica
Return to Zolazar for the final step. She will temporarily make Assara forces friendly toward you, allowing you to push through the final combat sequence.
Your objective is to clear the enemies around the Train Station and Radar Station, then deal with the Blue Eagle helicopter.
You can kill the pilot directly or destroy the helicopter. If you have Uluru’s rocket launcher, the final fight becomes considerably easier.
Once everything is cleared, the Harmonica will be delivered through your in-game mail. Put it into your EDC tool kit, equip it, and you’ll be able to manually play it.
Final Tips
The Longbow Valley Harmonica quest isn’t mechanically complicated—it’s mainly a test of patience, extraction discipline, and route planning. Remember the three biggest rules: finish each stage in order, extract after turning objectives in, and prepare for the next daily reset.
Follow the six-stage route above and you can add one of Delta Force’s strangest hidden collectibles to your collection without wasting raids.
