, his first game since ''
Assassin's Creed: Brotherhood'' (2010). The game was developed by Panache Digital Games, a studio opened in 2014 by game director
Patrice Désilets after he left
Ubisoft. Désilets focused on creating a toolbox for his new studio, which allowed characters to interact with the environment extensively. The team intended to create a game set in
prehistory so they did not need to build vast cities for players to explore. According to Désilets, he was "bored of the whole 10,000 BC [setting]", so he opted to create a game set ten million years in the past. To better study the setting, Désilets read books about
paleoanthropology, though some elements were exaggerated. Désilets designed the game to allow players to explore the game's various systems and features, which prompted them to use their instincts to look for solutions. The game does not have a structured narrative campaign, as Désilets hoped that players can craft their own experiences. Désilets envisioned the game as the first part of a trilogy, The game was announced at Reboot Develop 2015 in
Dubrovnik by Désilets. Initially, the game was
episodic, in which each chapter enabled players to "relive the greatest moments of mankind with a documentary twist". The decision was a financial one because the studio was small and it lacked sufficient funds to build a huge game. However, the plan was scrapped after
Private Division, a new
publishing label dedicated to supporting independent game developers, agreed to publish the game. The game was released for
Microsoft Windows on August 27, 2019 via the
Epic Games Store due to an exclusivity deal that would last for a year. The
PlayStation 4 and
Xbox One versions were released on December 6 of the same year. It was also released on the
Steam store in August 2020. ==Reception==
