Despite the previous entry in the franchise supporting cooperative play, developer Jason Paradise confirmed via the Steam forums that Far Cry Primal will not support co-op.
Since the game’s announcement, Ubisoft has been quiet not to reveal any sort of multiplayer elements. According to Paradise, the team made “the difficult choice of focusing our efforts on the single player experience” early on in the development process.
We are focusing entirely on creating the best possible Far Cry experience for our fans. Bringing the Stone Age to life and providing players with a strong gameplay experience based off of the Far Cry legacy meant we had to reinvent our core gameplay loop. This was definitely not a small undertaking.
