I have completed all missions and history played three times. With real-time and game-time without load saved games. But they have not unlocked the following Steam Achievements: Mars Conqueror, Half-Frame Frank, Dodgy Dave, Shaun Shifty, Life As We Know It, Curiosity Kills The Cat, Ancient Relic and Power Plant. I know How to do that but do not unlock achievements. Power Plant is locked in 1,048,576 / 1,000,000,000.
