Set in Opalia, a small kingdom in south-east Asia in the 1950s, Secret Mission plays out as you try to uncover evidence of the Minister's devious scheme. The country is caught in the middle of the Cold War between the USSR and the USA, with both superpowers vying for control.
The game challenges you with a variety of puzzles, including decoding messages and cracking safes, which are familiar staples of the adventure genre. With the help of voices and subtitles, you'll navigate through the story using only your keyboard to progress.
