Mastering the Root Cause Quest in Escape from Tarkov: A Complete Guide

The Root Cause task, presented by the Therapist during the Halloween 2024 event in Escape from Tarkov, stands as one of the game’s more challenging quests. This objective requires players to return to the containment block in search of a virus sample, which can be found in various spawn locations. Although you may have visited this area previously, you will need to extend your stay to thoroughly search for the required sample.

Challenges increase as lingering in this block for an extended period makes you susceptible to other PMCs (Private Military Companies) who may be waiting outside for an opportunity to strike, even amidst the relentless onslaught of zombies. Preparation is key to efficiently locating the virus samples without wasting valuable time. Below is a detailed guide on how to successfully complete the Root Cause task and the specific locations of potential virus sample spawns in Escape from Tarkov.

Completing the Root Cause Task in Escape from Tarkov

To successfully fulfill the Root Cause task, you must complete the following objectives:

Find and collect the virus sample in The Lab
Submit the collected item

The virus sample can appear at several spawn locations, all of which are conveniently situated within the containment block of the Labs. If you’re familiar with the area from previous quests, navigating it should be a bit easier.

When gearing up for this task, it’s advisable to use a similar loadout as you did in the “Burn It Down”quest but with additional Zagustins for enhanced protection. Consider equipping an Injector Case to store multiple stims without taking up excessive inventory space.

Initially, head to the computer room adjacent to the power switch within the containment block. In this room, check two specific areas for the virus sample: either to the left of the monitor near the vial case or to the right of the monitor on the desk.

If the sample is not found in these locations, be sure to check the bottom tray of the freezer situated in the corner of the room. These locations are your best bets for finding the virus sample in the computer room.

Your next target should be the laboratory room located on the left. Focus on the central large desk loaded with medical instruments; the vial may spawn directly in front of you. Feel free to jump on the desk to get a better view and check thoroughly.

Finally, proceed to the last laboratory room at the end of the containment block. Look out for the main table in the center, where the sample is likely to be located near the vial container. If you are playing alongside friends, rest assured that the sample will spawn in the same location for all players in the same raid.
