Interesting thing is, if this is actual game footage ( could be cgi ) is that it doesn't look like the creation engine and instead more like Id Tech 5 ( Rage, Wolfenstine ) or it could even be the Unreal engine
If it is Id Tech 5 then don't get your hopes up for modding. The amount of data required just to change a map is well beyond the standard moder.
Looking closer it does seem to be a updated creation engine. The blocky shadows on the dog etc.
