Atomograd

Atomograd is a point-and-click computer simulation game set in a Cold War-era Soviet nation. You play as an American agent who has broken into a Soviet air base in the region of Atomograd and must disable its nuclear weapons using an old 1980s computer.

Decrypt the computer

The computer's text and recordings are in a foreign language you do not recognize. You use a Morse-based messaging system and your ability to spot linguistic patterns to translate the language and work out how to disarm the nuclear warheads.

You search documents, video clips and chat logs for clues as you decrypt the computer and try to prevent nuclear annihilation.
