Ubisoft showed off some intimate gameplay from Far Cry Primal today in a live-stream they conducted to answer some questions about the upcoming prehistoric survival game.
During the stream they traversed through a system of caves to show off how they've made the game far more vertical in nature. You'll have a climbing claw to help you move up and down through the caverns and the rest of the outside world. The combination should give you a lot of options on how to approach conquering the world around you by giving you a more realistic, true to history, and challenging way to get around. And don't worry about getting lost, there'll be a tracking system to retrace your steps, like bread crumbs.
It was interesting to see the attention to detail paid to the design of this particular cave, with fireflies flitting about and the lighting from your torch dancing about the cave walls. If you want a more immersive experience you'll even be able to turn the HUD off completely.
