Based on the classic Ray Bradbury story, Sound of Thunder puts you in the role of Travis Dyer in a time-travel adventure where time is not on your side. The year is 2038, and a cult called Global Entropy has been traveling to the prehistoric past to destroy the present timeline as you know it. They appear to be successful, as Chicago is now under attack by various horrific prehistoric beasts and plants. Travel through four different time periods in nine combat and puzzle-filled missions to stop the cultists from completely annihilating your world. But be careful - even the most innocent-seeming action taken in the past can have huge repercussions in the present!
