Life is good in Far Cry new Dawn! And surprisingly authentic, as Ubisoft’s replica of a post-apocalypse landscape has some actual science behind it.

For Far Cry: New Dawn, Ubisoft wants to change that formula up and give players deadlier opponents to deal with. Thanks to enhanced enemy AI, the post apocalypse might just more ruthless as creative director Jean-Sebastien Decant detailed how the game world and its inhabitants would react to your incursions into enemy territory.

Nuclear winters look like no fun at all. According to Ubisoft’s research, while working on the concept for Far Cry New Dawn, areas affected by the aftermath of a nuclear explosion can spend six years hidden from the sun. Temperatures plummet, almost all signs of life vanish. If you’re not inside a bunker with food, clean water and board-games, you are f… doomed.

It has been 17 years since the bombs fell. Almost two decades of war and ruin, that has led to the world descending into chaos as a new status quo has risen up in the ashes of mutually assured destruction. Welcome, to Far Cry New Dawn.
