Countdown is a point-and-click adventure game released by Access Software for MS-DOS in 1990.

[1] The player plays as Mason Powers, a CIA agent who wakes up in a Turkish mental hospital, suffering from partial amnesia and accused of murdering his supervisor.

Powers must escape the hospital, find out who framed him, piece together his memory, and prevent terrorists from blowing up a peace conference.

The magazine wrote that excellent VGA graphics, sound, and controls made the game a "feature film" compared to the "mere cartoons" from Sierra On-Line, and compensated for the stock plot devices of amnesia and a protagonist falsely accused of murder.

Despite this, The One praised Countdown as "complex and substantial", and expressed that the game's espionage plot and exotic locations are 'engaging'.
