While most Grand Theft Auto IV mods do little more than add a stupid character to the game or mess with the visuals, this mod - called Desert Storm - does something way more drastic.

It covers the city in sand. Like, it buries the entire city in the stuff. In a very Spec Ops/Dubai kind of way.

You'd be forgiven for thinking it's just a cosmetic effect, but no. Stick with the video above long enough and you'll see people driving all over the stuff.
