Atomfall The Red Strain

The story of Rebellion’s Atomfall continues with The Red Strain, a new expansion available now for PS5, PS4, Xbox One, Xbox Series X/S, and PC for $19.99. It sees players venturing to Test Site Moriah, a new location with its own secrets and threats. Check out the launch trailer below.

Built on the remains of a missile testing facility by C.O.R.E., an unknown force has since taken up residence. Ultimately, the player can opt to venture inside, pick up any available leads and unravel what’s going on. It may have something to do with the red foliage surrounding the building, which is likely anything but good.

Players can look forward to new skills and weapons, including guns with suppressors and “heavy weaponry” from the new hostile robots. Something is lurking within Moriah and will seemingly challenge players unlike anything else before.
