Takkar, a hunter from the Wenja tribe, is the only survivor after his hunting party is ambushed and killed by a sabertooth, cutting him off from the rest of his kin. Resigned to proceed alone, Takkar meets Sayla , a Wenja gatherer whose life he saves, and once they arrive at Oros, Sayla informs Takkar that the Wenja are scattered and homeless across the land after their village was destroyed by Ull, leader of the Neanderthal-like Udam tribe who live in the northern mountains, prize warfare and hunting, and frequently kidnap Wenja to cannibalize them. Takkar then starts gathering the Wenja he meets around his cave, eventually encountering the wolf shaman Tensay, who helps him to learn the ability to tame the local animals. Tensay dubs Takkar the "Beast Master" for his skill.
As the game is set in prehistoric times, the traditional gunplay and vehicle gameplay featured in the Far Cry series were removed, and the player can only get access to melee weapons such as spears, clubs and ranged weapons such as bows and slings. The player cannot purchase weapons and must craft them using the materials scavenged in the world such as wood and stone. As the player progresses, they can craft more lethal weapons with a larger variety of resources. Besides facing natural dangers, the player must also compete with other hostile tribes occupying the area. By attacking and seizing bonfires and camps, the Wenja tribe will move in and begin patrolling the nearby region, and the player will gain fast travel points as well as camps to rest in.
