Guy's a beast, grabs the classic isometric look and artstyle and revitalizes it.
There's something about classic FO's artstyle that is so hard to emulate. the baked lighting and shading on models, the proportions. it's one of those things that only work from its isometric point of view, although his first person mock-ups are amazing. gives the classic look a spin to make it work in a 3D environment. strangely enough a game I think approached that look was the first RAGE.
