Assassin's Creed creator Patrice Désilets has given us another look at Ancestors, his studio's upcoming third-person survival title that's set 10 million years ago in Africa.

The game is pitched as the early story of mankind with a documentary twist: "humanity is one idea away from evolution or extinction."

Speaking at Reboot, Désilets revealed that the game will no longer be released in episodes, and that it has grown in size since its announcement at E3 in 2015.

"It was hour to hour, now it's open and I let the player tell their own stories," he said.

"There are systems talking to each other, not me taking players by the hand. You'll create the story of your own ancestors, and maybe it will be different than what science claims."

"We're all big apes, that's what we are," he added.

"We're mutants that live in a fast-paced technological place, but that's not what we are. We're made out of the jungle, that's why we're scared of everything. We're good at fleeing. That's why we're afraid of talking in front of people, missing the train."

Although there are no swords or walls, gameplay-wise Ancestors is similar to Désilets' other games.

"I do third-person games," he said.

"I don't do VR. I do Assassin's Creed, Prince of Persia type of games, and my next 15 games will be in the same vein – if I don't die in the meantime."

However, Desilets said he is steering clear of the typical "hero's journey" structure.

Desilets' other game, 1666: Amsterdam, is currently on hold – not cancelled. It was originally to be published by THQ, then was picked up by Ubisoft, before he reclaimed it.
