As long as you're not expecting the ultra realism that is to be expected from a Forza Motorsport game, you'll find that Unbounded looks fantastic. It sports a consistently dark and shiny aesthetic that encompasses every part of the game's presentation. The sense of speed lies somewhere between the fantastical and the realistic, which is apt. The destruction physics are absolutely ridiculous; obstacles that would rend normal vehicles into tin foil are completely pulverized on impact. Chunks and bits of debris scatter all over the track, and fragged cars literally go to pieces as they roll down the road. Displays of your position, lap, and distance from the leader are superimposed on the landscape, much like the objectives in Splinter Cell: Conviction. Load times are minimal, and if you want to retry an event, you won't have to load at all. It's great.
Someone at BugBear Entertainment really likes dubstep. Unbounded's soundtrack is full of bass drops and other assorted electronic chaos. To be fair, Skrillex's "Kill Everybody" is a pretty good track to level parts of a city to. You've got total soundtrack control, as well; if you don't like a particular song, you can flip through it as you race. The rest of the game sounds great. Cars sound angry (if not fierce) and I have to wonder just how the developers were able to replicate the sound of buildings and other collateral damage being destroyed.
