How is this done?

Hey, i found this image on the 2advanced website and wondered if you could tell me how this was done, software wise? Thank you]

See Image

well looks like a mix of a 3d software, photoshop and even a vector app or maybe the 3d objects were rendered with a toon or vector renderer. but its usually 2 main apps for this sort of image, 3d , photoshop.
