'Ancestors: The Humankind Odyssey' is a new game with a plot that's at odds with its ambitious technical scope. Though the game is being teased as a massive, open-world format that only the most modern systems could run, it's subject is prehistoric. The game revolves around the evolution of humankind itself, with the story set between 10 and 2 million years ago.
Ancestors: The Humankind Odyssey is being developed by Patrice Desilets, who was the creative director on the tremendously successful 'Assassin's Creed' and 'Assassin's Creed 2' games (which have spawned several sequels as well as a Hollywood movie starring Michael Fassbender.) Seeing that the Assassin's Creed franchise focuses on the past, it is fitting that Desilets is reaching back through the sands of time once again.
The current teaser for Ancestors emphasizes that it is pre-alpha footage, so the game's release date is likely still a ways away (albeit nearer to us than the characters the game portrays.)
