What is Nuclear Nightmare?

Nuclear Nightmare is a first-person survival horror game set in an open Arctic world, playable alone or in online co-op. You scavenge weapons and supplies, test teammates and huskies for infection, recover information about a virus, and gather what is needed to call an evacuation helicopter before a nuclear strike.

For you if...

  • +you want co-op horror built around infection and mistrust
  • +you enjoy open-world scavenging under a strict deadline
  • +you like limited inventories and resource management

Not for you if...

  • −you prefer guided levels over open-world exploration
  • −you want combat without sudden difficulty spikes
  • −you mainly want a relaxed single-player horror game

What players say

80% of 16,665 reviews are positive · 82% of 387 in the last 30 days

Players most often praise the snowy horror atmosphere, infection-driven uncertainty, and chaotic co-op with friends. The dominant complaints are pervasive bugs, crashes, poor optimization, connection problems, and inconsistent combat and enemy behavior; several players also find driving awkward and difficulty poorly balanced.
