ATOM RPG is a post-apocalyptic role-playing game from indie studio AtomTeam, released in December 2018 for PC and Mac. It is openly inspired by the classic computer RPGs of the past — Fallout, Wasteland, Deus Ex and Baldur's Gate. You play an operative of the secret ATOM organisation, sent into the Soviet wasteland nineteen years after a nuclear war to find a lost expedition and investigate a conspiracy. Expect a large hand-built world, turn-based combat and choices that change the story.

Key Features

  • A large post-apocalyptic world with towns, wilderness and hidden locations to explore
  • Turn-based tactical combat built on a classic SPECIAL-style character system
  • Deep character creation with skills, traits and many possible builds
  • Branching quests and dialogue where choices and skill checks matter
  • Crafting, survival elements and a distinctive Soviet-era atmosphere

How to Download

  1. Install the Steam client on your Mac and sign in to your account.
  2. Get the game from its official store page: Download from the official site
  3. Buy or redeem the game, download it through Steam and launch it from your library.

System Requirements

ATOM RPG is a modest game by modern standards and runs on a recent version of macOS with a mid-range Intel or Apple silicon Mac and a few gigabytes of free storage. Check the system requirements on the Steam store page for the exact minimum for the current build.

FAQs

Is ATOM RPG like the old Fallout games?

Yes, that is its stated inspiration: an isometric viewpoint, turn-based combat, skill-based dialogue and a bleak but often darkly funny wasteland, presented as a Soviet counterpart to that setting.

How long is the game?

It is a substantial RPG. A thorough playthrough with exploration and side quests can take several dozen hours, and different character builds open different solutions and endings.
