Can You Stop the Red Strain?
The Red Strain takes you to a new region in the Quarantine Zone – Scafell Crag. Here you will find Test Site Moriah, a secret research site built by B.A.R.D on an old missile testing facility. Nestled in the hills away from prying eyes, it has been shrouded in mystery ever since it became operational.
A deadly virus has infected the region, and it is seeping out from a secret network of underground labs and bunkers. It’s up to you to explore the sprawling area and unravel the mystery of what really happened at Test Site Moriah – and try to find a way to eliminate the Red Strain.
While investigating the site you will uncover new leads that intertwine with the Atomfall narrative and may ultimately unlock new endings. New characters will help to guide you through the mystery, while a variety of infected and mechanical enemies could bring your adventure to an untimely end.
There are also new tools and weapons for you to discover, as well as additional skills to learn along the way, which can transform the way you play every region of the Quarantine Zone.
How to Get Started in The Red Strain
Firstly, you need to find Scafell Crag… The route there can be found by exploring the Slate Mine Cave, where you will find an old B.A.R.D. lift. You may well have found this location while playing the main game through access points in both Slatten Dale and Skethermoor. The cave is home to trader, Reg Stansfield.
We don’t want to spoil too much – but when you arrive in the new area you will find yourself at an abandoned train station where a mysterious voice will speak to you over the speaker system, giving you your first Lead and directing you to Test Site Moriah. Between the station and Moriah, you will find a nearby abandoned village to explore, complete with the ruins of shops and a pub – and the surrounding area is crawling with infected soldiers, villagers, and even worse, so you need to keep your wits about you.
Your first major challenge is going to be getting access to the site from the village. The gate is heavily guarded by B.A.R.D hardware, so be sure to pack your Rewiring Tool!
Once inside you will find several top-secret research facilities to explore, each giving you an insight into what happened at the test site, and what secretive project got out of control. From here the story of the Red Strain and the mission codenamed ‘High Albion’ begin to unfold.
Be prepared to face a barrage of new threats and enemies, including an upgraded robot, complete with an induction launcher which deals incredible damage once they lock on. However, by finding (or crafting!) training stimulants you will be able to unlock vital new skills, including the ability to equip the heavy weaponry wielded by the robots found throughout the Quarantine Zone, turning their awesome firepower against your enemies.
There is far more for you to discover as you explore Test Site Moriah in search of answers and a way to escape the Quarantine Zone – but we don’t want to spoil the fun by revealing too much!
Atomfall is playable today with Xbox Game Pass, PC Game Pass, and available for purchase through the Xbox Store. The new Red Strain expansion pack is also available to buy now.

Atomfall Story Expansion Pack: The Red Strain
Rebellion
Nestled in the hills, away from the prying eyes of the locals, lies Test Site Moriah. A secret research station built on the site of an old missile testing facility, it has been shrouded in mystery ever since it opened. But something changed when the quarantine came into effect and the facility has fallen into more nefarious hands who are keen to keep its secrets for themselves. Now a route back into the facility has been located, and with it the opportunity to finally get some answers.
Investigate Test Site Moriah
Before the Windscale Disaster, the research site was home to top-secret government projects, so classified that even those at the top of B.A.R.D were unaware of their existence. Now the facility lies forgotten, deliberately sealed away from the rest of the Quarantine Zone. What secrets rest behind the locked doors? Only you can find out.
A new story in its own right, The Red Strain offers original leads that interlink with Atomfall’s core narrative, expanding the story and unlocking new endings to your adventure.
Enhance your Arsenal
Enhance your experience with a variety of new skills and equipment. Strike from the shadows with new suppressed firearms or unlock the ability to equip the heavy weaponry from disabled robots and unleash devastating attacks on your enemies.
Fight for Survival
A terrifying new threat, never encountered before enemies and challenging obstacles await you, offering an immense challenge. You will need to have your wits about you if you are to have any chance of making it out alive.
