For many raiders, the Testing Annex in the Dam Battlegrounds is the sweet spot between safety and reward. Though smaller than the Hospital, this two-story facility offers dense loot spawns, especially on ARC Raiders Coins the second floor, which is packed with medical drawers and desks.
The Testing Annex's mix of lootable containers makes it a great place to collect Laboratory Reagents, Rusted Shut Medical Kits, and Antiseptic. Its compact layout also makes it easier to loot quickly and extract before anyone else arrives.
The ARC presence here can vary - sometimes the area is eerily quiet, while other times, drones and patrols might sweep the perimeter. Move cautiously, check corners, and always listen for audio cues that might give away nearby enemies or players.
Areas to Avoid
Not every zone in Arc Raiders is worth your time if you're specifically farming Medical materials. In particular, Spaceport and The Blue Gate have no dedicated Medical loot spawns. While they're great for scavenging general resources, they're a waste of time for anyone hunting Laboratory Reagents.
Stick to the three Medical hubs listed above if you want to maximize efficiency.
Farming Tips for Laboratory Reagents
Bring a Safe Pocket Augment – Always store your Laboratory Reagents in your safe pocket the moment you pick them up. If you die before extraction, you'll still keep them.
Use Headphones and Night Mode – Sound is crucial for avoiding ambushes. Night Mode helps boost subtle noises like footsteps and ARC drones.
Go Solo for Efficiency – Solo runs often yield more loot per minute with fewer player conflicts.
Check Second Floors First – In both Hospital and Testing Annex, upper levels tend to contain denser medical loot spawns.
Don't Rely on RNG Alone – Even with perfect conditions, Laboratory Reagents aren't guaranteed. Some runs will simply be unlucky - persistence is key.
Final Thoughts
Upgrading your Explosive Station in Arc Raiders is one of the most rewarding crafting goals for demolition-minded players, and Laboratory Reagents are an essential part of that journey. Whether you're methodically combing through the Hospital's hallways, sneaking through the quieter Research building, or making quick raids at the Testing Annex, knowing where to look will save you hours of frustration.
Remember: in Arc Raiders, surviving long enough to extract with your loot is half the battle. Be patient, plan your route, and keep your wits about you. Having sufficient ARC Raiders Coins will also be of great help to you. With a bit of luck (and maybe a few explosions along the way), you'll have all the Laboratory Reagents you need to build the ultimate explosive arsenal.
The Reduced to Rubble quest in Arc Raiders can be surprisingly confusing the first time you take it on. On paper, it sounds straightforward-take a photo and follow a trail-but when you're surrounded by debris, chaos, and scavengers in Olive Grove, the vague objectives can make it difficult to know where to start. The quest doesn't clearly tell you what "photographing" means, nor where exactly the "trail of destruction" is supposed to lead.
If you've been wandering around aimlessly trying to figure out what to do, don't worry. This guide will break down every step of the Reduced to Rubble quest, including the precise locations you need to visit and what to expect along the way.
Quest Overview
The Reduced to Rubble quest takes place in the Blue Gate area of the map. It involves two main objectives, broken down into four quest stages. You don't need to complete everything in one raid session, and there's no need to bring any special equipment or extract with ARC Raiders Items-just focus on exploration and survival.
However, be warned: the trek will take you through Olive Grove, a dangerous and highly contested region. Many players farm this area for valuable resources like lemons, apricots, and olives, so expect to encounter other raiders while completing the objectives. To reduce the risk of losing valuable gear, it's best to enter with a free or lightweight loadout-you won't need heavy weapons or rare items to get the job done.
Objective 1: Photograph the Collapsed Highway
Your first goal is to photograph the collapsed highway located on the west side of the Highway Collapse area.
When you approach the site, move slightly north of the Highway Collapse map marker. You'll find the interaction point between a tree and a large rock, right where the highway visibly crumbles into buy ARCR Coins the ground.
