enhanced physics and weather dynamic!
"weather patterns develop dynamically,so while you play the game,the weather kicks in and you can see cloud formations changing.you'll witness a sort of darkness,and ambient light changing from all directions,because we wanted people to see the world transforming and really coming alive.So for example ,rain and thunder might kick in ,and the raindrops will make surface wetter and depending on the wetness,the properties of physics on those surfaces will change accordingly.The goal has been to create atmospheric changes relativ to the enviroment that are as real as possible,so that means things like wind and rain physics, day/night cycles and tornados"

"
Every object in the game will cast a shadow, everything will interact, and everything will exist and adapt in realtime, from weather and light cycles to vegetation. Enemy units not only exhibit an advanced model of visual perception, but also a dynamic aural acuity. Both senses are adaptive, different surfaces or sharpening the sound that the AI reacts to.
Every shadow has a disguise property that changes relentlessly with the passage of clouds, or any other obstruction, before the sun or moon.Every single polygon of vegetation is independently affected by wind , and movement through it will part it in ways that the AI can recognise. Moreover, it is entirely destructable."

sogar so sachen wie regen werden durch den wind beeinflussbar sein!
irgendwelche Fragen noch? wir haben es hier nicht mit einer 0815 engine zu tun also bitte leute
