Finding Lemons: The Fruit of Your Labor
Lemons are surprisingly abundant in Arc Raiders—if you know where the trees grow. You’ll need three lemons total, making this the most time-consuming part of the quest due to the quantity required.
Dam Battlegrounds Route
Head to the South Swamp Outpost area and navigate toward the Hydroponic Dome Complex. This location features multiple Lemon Trees that spawn with decent frequency. The key is thoroughly searching the entire complex rather than expecting trees in exact spots every time.
Blue Gate Alternative
If Dam Battlegrounds isn’t yielding results, try Blue Gate’s Olive Grove area on the southern portion of the map. It’s positioned directly left of the Farmlands POI, making it easy to locate. The Olive Grove provides another reliable lemon-spawning zone.
Pro Tip: Lemon Trees spawn randomly in areas tagged with the “Nature” category in POI descriptions. Use your map filters to identify these locations and increase your success rate significantly.

Securing the Water Filter: Buried City Mission
The Water Filter requires a trip to Buried City, specifically to Plazza Roma. This item has a fixed spawn location, making it far more predictable than the lemons.
Navigate to the southwest side of Plazza Roma and locate the prominent building in that corner. Scale to the rooftop where you’ll find an interactive machine. Interact with this device to reveal and collect the Water Filter component.
The relatively low threat level in this area means you can focus on extraction rather than combat, though always remain vigilant for other players in Arc Raiders’ competitive environment.

Water Pump Hunt: Industrial Expedition
The Water Pump proves to be the trickiest item due to its random spawn nature within industrial locations. Return to Dam Battlegrounds and filter your map to show Industrial-category POIs.
You’ll need patience for this final item. Water Pumps spawn randomly inside crates and containers throughout industrial buildings, so methodical searching is essential. Check every corner, loot every container, and don’t skip any potential spawn points.
Search Strategy: Start at one industrial site and systematically clear it before moving to the next. This prevents accidentally revisiting areas you’ve already searched and maximizes efficiency.
Extraction and Turn-In
After collecting all required items, successfully extract from your raid with all three items intact. Losing them during extraction means starting over, so prioritize survival over additional loot once you have everything.
Return to Speranza and locate Trader Tian Wen. Hand over the lemons, Water Filter, and Water Pump to complete the quest and claim your rewards.
Quest Rewards Breakdown
Completing Unexpected Initiatives provides substantial benefits:
28,000 Experience Points: A significant XP boost that helps level progression and unlocks new content
Osprey I: A valuable piece of equipment that enhances your raiding capabilities for future missions
These rewards make the multi-map scavenging effort worthwhile, especially for players looking to optimize their loadout and progression.
Time-Saving Tips
Map Selection: Start with Dam Battlegrounds since you need items from two different locations on this map (lemons and Water Pump)
Nature POI Priority: Always check Nature-tagged areas first when hunting lemons
Industrial Efficiency: Visit Industrial POIs during off-peak hours to minimize player competition
Team Coordination: Running this quest with teammates allows you to split up and cover more ground simultaneously
Backup Plans: Know multiple spawn locations for each item before starting your raids
Common Mistakes to Avoid
Don’t rush through industrial buildings when searching for the Water Pump—thoroughness beats speed here. Many players give up too quickly, assuming the item isn’t present when they simply haven’t checked every container.
Avoid carrying valuable loot when on quest runs. If you’re killed before extracting, losing additional gear compounds the frustration. Travel light and focus solely on quest objectives.
Remember that lemon trees don’t always spawn in the exact same spots. Check the general area rather than expecting a specific tree location.
Why This Quest Matters
The Unexpected Initiatives quest serves as excellent practice for Arc Raiders’ core gameplay loop: scouting locations, gathering specific resources, and successfully extracting under pressure. The substantial XP reward accelerates your progression, while the Osprey I equipment provides tangible benefits for future raids.
Frequently Asked Questions
Q: What are the exact locations where I can find all three lemons needed for the Unexpected Initiatives quest in Arc Raiders?
A: Lemons can be found at two primary locations: In Dam Battlegrounds, head to the South Swamp Outpost area and search the Hydroponic Dome Complex for Lemon Trees. Alternatively, visit Blue Gate’s Olive Grove on the southern side of the map (directly left of the Farmlands POI). Since Lemon Trees spawn randomly in Nature-category POIs, use your map filters to identify these areas and check multiple spots. You need three total lemons, so thoroughly search the entire area rather than expecting trees in exact locations every time.
Q: Where do I find the Water Filter and Water Pump to complete the Unexpected Initiatives quest?
A: The Water Filter has a fixed spawn location in Buried City at Plazza Roma. Navigate to the building on the southwest side, climb to the rooftop, and interact with the machine there to obtain it. The Water Pump spawns randomly in Dam Battlegrounds within Industrial-category POIs. Search through all crates and containers in industrial buildings—this requires patience as the spawn is random, but checking every corner systematically increases your chances. After collecting all items (3 lemons, 1 Water Filter, 1 Water Pump), extract successfully and return to Tian Wen in Speranza to claim your 28,000 XP and Osprey I reward.
