Interesting layout, and I like the diagonal steps - it's a nice novelty, you don't see much in the way of diagonal things in CS2D. Looks a bit open in places, but I haven't seen the original so I can't really judge too much.
@ Andrez: I don't really understand why. Car is a wall, boxes are walls, you got corridors to hide in, area isn't square so terrain itself provides cover. Good to get feedback, thanks.
