The next stop is Piazza Roma, located a short distance northeast of Grandioso Apartments. This section of Buried City features multiple tall structures, but the one you're looking for ARC Raiders Coins has a distinct rooftop garden space where the Water Pump is located.

Compared to Grandioso, Piazza Roma sees less raider traffic, which gives you a more relaxed window to complete the objective-though it's still wise to stay alert.

Finding the Correct Building

When you reach Piazza Roma, identify the building shown in the original quest screenshot or map marker. It is recognizable by:

A garden rooftop

Clustered planters

A clear path to a higher ledge

Climbing to the Rooftop

The most efficient way to reach the Water Pump is via:

A yellow ladder is located between the target building and the structure beside it

This ladder climbs multiple levels and takes you directly to the roof. You can traverse the building internally, but the ladder is significantly faster and safer.

Locating the Water Pump

Once on the roof:

Head toward the corner with the large planters

Look for a small, box-like machine connected to pipes

Interact with it to loot the Water Pump

Stow this item in your second safe pocket before preparing to extract.

Extracting Safely After Collecting Both Items

With both quest ARCR Items secured, you only have one task remaining: escape Buried City in one piece.

Choosing the Best Extraction Route

Depending on your position after looting Piazza Roma, the closest active metro stations may include:

The western station near Grandioso

The central Buried City station

The northeastern access station

Check the map for which stations are currently open. Prioritize routes with:

High cover density

Multiple escape paths

Low expected raider traffic

Move quickly but carefully. Buried City is notorious for ambushes near train platforms.

Securing Your Extraction

Once you reach an active station:

Activate the metro console

Take cover until the train arrives

Board quickly and interact with the onboard extraction terminal

If you placed the Fertilizer and Water Pump in safe pockets, even an end-of-run ambush shouldn't ruin your progress.

Turning In the Quest

Return to Speranza and speak with the quest giver to finish Unexpected Initiative. Completing this mission advances you further into the Buried City questline and unlocks additional objectives tied to its world-building and faction developments.

ARC Raiders: All Loot Crates and Rarity Levels
The Rust Belt is packed with opportunities for valuable loot in ARC Raiders, but not every container you crack open will reward your efforts. Understanding how loot rarity works-and knowing which crate types are actually worth your time-can dramatically improve your haul each time you head topside. Whether you're searching for weapons, rare ARC components, or upgrade materials to take back to Speranza, this guide breaks down every major loot container and the rarity tiers you should be chasing.

Understanding Loot Rarity in ARC Raiders

Every item you find in ARC Raiders falls into one of five color-coded rarity levels:

Common (White)

Uncommon (Green)

Rare (Blue)

Epic (Pink)

Legendary (Gold)

As a general rule, higher-rarity gear will outperform ARC Raiders Items of lower rarity. This is especially true for weapons, shields, and Augments-these upgrades scale strongly with rarity and are always worth bringing home. That said, there are a few exceptions. Some crafting materials you need for early game upgrades are intentionally low-rarity, so don't write off common items if you're missing essential components.

Rare ARC materials follow a different pattern. They scale in rarity based on the difficulty of the ARC enemies they come from, so tougher drone types naturally provide more valuable parts. Trinkets are another wildcard: they come in many rarities and can be exchanged for large amounts of cash in Speranza, making them great for financially focused raiders.

The bottom line: if it's a high-rarity weapon or Augment, take it. If it's a crafting component, rarity may not matter as buy ARCR Coins much, but ARC components are always worth grabbing.
