Assassin's Creed Shadows' gameplay will be affected by Ubisoft's fancy new weather tech, and the studio says its future games will incorporate it "in much more depth"

The weather in Assassin's Creed Shadows is a pretty big deal for Ubisoft, mostly due to a fancy new tool called Atmos that allows for fully simulated weather that affects gameplay.

Talking to VG247, Assassin's Creed Shadows art director Thierry Dansereau said there's a big focus on the game's skies because they "represent a major visual element that greatly contributes to the perceived visual quality and level of immersion." Dansereau added that the simulation of realistic clouds will help Ubisoft bring to life a "dynamic world that is in constant transformation."

So, what exactly is different about the way Ubisoft is designing Assassin's Creed Shadows' skies compared to earlier games in the series? Well, apparently it all comes down to that Atmos tech I mentioned at the start of this article.

"In AC Shadows, the entire weather is simulated, which means that the clouds are dynamic, and they evolve over time," explained Assassin's Creed Shadows tech lead Maxime Beaudoin. "[...] Atmos not only drives the clouds that you see in the sky, but the entire weather as well (precipitations, wind, wetness accumulation on the ground, thunder strikes, etc)."

Beaudoin said these weather effects aren't just for lookin' at - they also will have a real impact on gameplay. It's unclear to what extent, exactly, but Beaudoin said NPCs will have a tougher time detecting the player during thunderstorms because of all the noise and reduced visibility.

The Atmos tool also means artists don't have to manually create and script clouds and various weather effects; Beaudoin said they only have to "tweak a few parameters, and a cloudscape emerges automatically."

"This means that they don’t control the exact shape of the clouds like in previous games; instead, they focus on the composition, determine the overall look they want to achieve and let the simulation fill in the gaps. This makes it possible to create a very realistic looking cloudscape in a matter of minutes."
