'Observation' is a tense, atmospheric puzzler where you play a modern HAL 9000

When you watch 2001: A Space Odyssey, do you find yourself criticizing HAL 9000's machinations and thinking, "I could do better than that!" If so, Observation may be right up your alley. In it you play a space station AI called SAM that is called upon by the humans on board to help resolve a deadly mystery — though you may be a part of it yourself. The game takes place in the near future on board the titular space station, a sort of expanded version of the ISS.
