During the critical Dr. Garrow investigation storyline in Atomfall, players encounter a pivotal mission requiring access to classified files stored within the Dam Data Store facility. Dr. Garrow specifically instructs you to execute the ERA Command on their computer system while explicitly prohibiting examination of documents related to the recent Windscale incident. This assignment directly follows the research file retrieval task completed in the Interchange district.
Contrary to initial expectations, the Dam Data Store isn’t situated within the Interchange area. Instead, you must travel to Casterfell Woods to locate and enter this secure data repository. Our comprehensive guide provides detailed navigation and strategic approaches for successfully completing this challenging segment of Dr. Garrow’s investigation.
Your initial objective involves locating and entering the Dam Data Store within Casterfell Woods. The precise coordinates are 22.5 E, 92.4 N. You’ll recognize the facility by its distinctive large green doors positioned at the base of an abandoned quarry excavation site.
Upon entering the structure, you’ll discover an extensive server farm facility with data storage units lining all wall surfaces and a formidable automated security robot systematically patrolling the central area. Neutralizing this mechanical threat should be your immediate priority, as its persistent presence significantly complicates navigation and puzzle-solving activities. For players unfamiliar with robotic enemy tactics, our specialized Weapons Unlock guide includes effective countermeasures against automated defenses.

After disabling the robotic sentry, ascend the staircase located in the rear left section of the main chamber. Here, utilize your Signal Redirector tool to bypass the electronic locking mechanism on the right-side wall panel. Adjacent to this mechanism, you’ll discover a technical notice indicating complete power shutdown throughout the Dam Data Store complex. Your primary responsibility becomes restoring electrical systems to operational status for ERA Command execution.
Pro Tip: Approach robot encounters strategically by utilizing EMP grenades or hacking mini-games for quicker neutralization than conventional firearms.
After gaining access to the secured room atop the staircase, employ your Signal Redirector to reroute power from the junction box to external systems. Carefully monitor energy flow directions, as you’ll be sequentially transferring electrical current between multiple junction boxes over several minutes. Once you’ve successfully redirected power outside the initial room, return to the main area and locate the newly activated junction box mounted on a nearby support pole.

This specific junction box activates a laser-based automated defense turret. Quickly descend the staircase and utilize your Signal Redirector on this junction box to deactivate the laser system. This action transfers energy to another junction box positioned on the facility’s ceiling structure. To access this elevated box, climb onto adjacent server racks in the room’s center and position yourself directly beneath it. Use the Signal Redirector again to transfer power, which subsequently activates another laser defense mechanism.
Trace the junction box wiring across the ceiling framework, requiring additional server climbing to reach subsequent junction boxes for continued power redirection. Persist in following the energy pathway until it ascends into the control room situated opposite your initial entry point. Ascend to this control room, utilize the Dam Data Store Keycard on the central console’s locking mechanism, which activates the Data Interface Console computer located directly beneath the control room.
Common Mistake: Players often miss the ceiling junction box, causing unnecessary delays. Always scan vertical spaces thoroughly when power seems interrupted.
Once the Data Interface Console achieves full operational status, exit the control room and approach the now-illuminated computer terminal on the main level. Initiate interaction with the console, but remain vigilant, as hostile rat swarms frequently attack during this interaction sequence. If this occurs after you’ve begun computer interaction, the interface doesn’t permit exiting to combat the rodents, making preemptive area clearance essential.

Strategic Insight: Experienced players recommend clearing the area of all potential threats before initiating computer interaction. The Class Guide provides additional tactical approaches for area denial and enemy management.
Successfully executing the ERA Command completes this phase of Dr. Garrow’s investigation. Return to the doctor with your mission accomplishment confirmation. For comprehensive gameplay strategies beyond this specific mission, consult our Complete Guide to Atomfall’s mechanics and narrative progression.

Time Estimate: Allocate approximately 15-20 minutes for skilled players to complete this mission segment, while newcomers might require 30-45 minutes depending on combat proficiency and puzzle-solving speed.
