About Atomfall Story Expansion Pack: The Red Strain
Atomfall Story Expansion Pack: The Red Strain adds a new location, enemies, quests, characters, items, weapons and more to Atomfall. At Test Site Moriah, a secret research station built on the site of an old missile testing facility, you investigate what happened after the quarantine left it in the hands of people determined to keep its secrets.
Test Site Moriah
Before the Windscale Disaster, the facility housed top-secret government projects so classified that even senior members of B.A.R.D did not know about them. Now it lies sealed off from the rest of the Quarantine Zone. The expansion has its own story, with original leads that connect to Atomfall’s main narrative and unlock new endings.
New equipment
You can use new skills and equipment, including suppressed firearms for stealthy attacks. You can also equip heavy weapons taken from disabled robots and use them to unleash powerful attacks on enemies.
New threats
The expansion introduces a terrifying threat, enemies you have not encountered before and challenging obstacles.
