Unexpected Initiative Arc Raiders Guide: How To Find Fertilizer And The Water Pump In Buried City

If you’ve been grinding Arc Raiders long enough, you already know that some quests flow naturally, while others feel like they were designed at 2 a.m. after too much coffee. Unexpected Initiative falls right into that second category. It’s one of those quests that technically makes sense once you understand it, but the first time through? It can be confusing, janky, and downright annoying.

The issue is simple: even if you’ve already collected Fertilizer and a Water Pump in previous raids, the quest still demands you loot the designated versions located in two specific POIs during a single Buried City run.

This guide breaks down everything you need to know to complete Unexpected Initiative Arc Raiders quickly and painlessly. We’ll go step-by-step, location by location, using clear veteran logic.

Let’s dive in.

What Makes the Unexpected Initiative Quest So Confusing

Here’s the part Arc Raiders never explains well: the quest will not count unless you physically interact with the quest-specific Fertilizer and Water Pump in Grandioso Apartments and Piazza Roma, during the same raid.

It doesn’t matter if you already have ten Water Pumps sitting in your stash. The system ignores them.

That’s why so many players think the quest is bugged. It isn’t—it just follows extraction-shooter logic. To complete it, you’ll need to:

• Visit both POIs in one run

• Interact with the correct objects

• Pick up the dropped items

• Extract safely

I highly recommend running an augment with two safe pockets. You may not need them for completion, but they’ll save your sanity if another raider interrupts your run.

Where To Find Fertilizer

Grandioso Apartments Rooftop Location

Your first stop is the Grandioso Apartments, located on the west side of Buried City. It’s a high-traffic residential POI—meaning you’ll often find other players passing through looking for loot, fights, or easy picks.

Move carefully here.

Once you arrive, head inside the building and take the inner lift shaft upward. There’s a zipline running inside the shaft that leads to the upper floors. After exiting the zipline, climb the stairs to the rooftop.

On top, you’ll be looking for orange soil-filled terracotta pots. The Fertilizer can spawn in either:

• The southern corner of the rooftop

• The northeastern corner of the rooftop

Both spawn points are easy to recognize thanks to the yellow interaction icon. Once you interact with the planter, Fertilizer drops beside it. Pick it up immediately and pocket it.

Don’t linger on this roof longer than necessary—any experienced raider knows how exposed this area is.

How To Reach Piazza Roma Quickly

Moving Safely With the Fertilizer

The good news: Piazza Roma isn’t far. It sits a short trek northeast of Grandioso Apartments, making this route one of the more straightforward quest paths in Arc Raiders.

Piazza Roma has fewer visitors compared to Grandioso Apartments, but don’t assume it’s empty. Anyone else doing Unexpected Initiative will be hitting this same spot.

Your goal is a large residential building south of the Piazza Roma text label on the map. There are two ways to get to the rooftop:

• Take the yellow external ladder between the buildings

• Climb through the building interior via the usual stairs and ziplines

Take the ladder. It’s faster, safer, and has fewer ambush angles.

Where To Find the Water Pump

Broken Rooftop Gardens at Piazza Roma

On the rooftop, you’ll find the Water Pump in one of two locations:

• The northwest corner of the roof

• The southeast corner of the roof

Both look the same: a glass tank connected to a small motor and hose stuck into a planter bed. The interaction icon makes it easy to spot.

Interact with the water system, the Water Pump will drop onto the ground, and you’ll pick it up the same way you grabbed the Fertilizer.

At this point, you're halfway done—but the quest isn’t complete until you're out safely.

Extracting Without Losing Everything

Smart Exfil Tips For Arc Raiders Veterans

Piazza Roma is blessed with a nearby metro station, and if it’s active, it makes for a clean extraction. But extraction is where most Unexpected Initiative runs fall apart.

Here’s how to avoid unnecessary frustration:

• Listen for gunshots or footsteps before committing to the metro

• Don’t sprint across open plazas or long rooftops

• If enemy players appear uninterested in fighting, don’t provoke

• Track ARC drone routes before moving groundside

• If extraction is unsafe, rotate to another metro or evac route

Losing both quest items means restarting the entire run, so patience is absolutely worth it.

Why This Quest Feels So Strange

Unexpected Initiative Game Logic Explained

The reason this quest feels odd is because Arc Raiders normally lets you complete item-based tasks using items from your stash. Unexpected Initiative breaks that rule.

Instead, the quest is intentionally designed to push you through two major rooftops and force a multi-objective route through Buried City in a single raid.

From a gameplay perspective, it teaches:

• Vertical navigation

• POI familiarity

• Safe extraction tactics

• Multi-step objective awareness

From a player perspective? It can feel janky the first time—but once you know the route, it becomes a quick and easy run.

Veteran Tips To Complete Unexpected Initiative Cleanly

Here are the tips that consistently make the run smoother:

• Always start with Grandioso Apartments

• Don’t rush across loud surfaces on rooftops

• Check skyline silhouettes for player movement

• Use the yellow ladder in Piazza Roma—it’s the best option

• Keep the route tight and predictable

• Approach every corner with the expectation of other raiders

• Treat extraction as a separate objective, not an afterthought

Follow this routine and you’ll breeze through the quest with no confusion.

Final Thoughts

Finishing Unexpected Initiative the Easy Way

And that wraps up this Unexpected Initiative Arc Raiders guide. Once you understand the quest’s quirks, it becomes simple:

• Hit Grandioso Apartments

• Grab the Fertilizer

• Move to Piazza Roma

• Pick up the Water Pump

• Extract without panicking

After that, turn everything in and move on to the better quests Arc Raiders has to offer. If you're aiming to gear up, craft more efficiently, or upgrade loadouts, this is also a good time to look into Arc Raiders items for optimizing your build.
