I know this scene is part of a video game. Don't ask me the name of the game because the only games I played were Space Invaders and PacMan :D. But, yes, it's a video game. Of course, this is my 3D version, which isn't, far away, as good as the original one. For this reason I categorized the render as Fan Art, just in case. Renderized with Cycles. Images packed. Regards, Blender artists.
P.S.: There isn't any animation, at all. Just still image.

Hi, Ninjak. The "grime" of the ladder just takes the glossy shader and noise texture. Play with them and you'll get it. The illumination also adds its effect. Regards.
A really good recreation! I'd like to know how you did the grime on the ladder, because I have a scene where I need to texture a ladder like that :)
