(Jyri Jokinen, 16.07.2008 - 00:00) FlatOut: Head On is ready to drop the hammer on the PSP extreme racing genre, bringing high speed destruction and leaving more broken bones and wrecked cars in its wake, than a Richard Hammond Top Gear stunt. From rock-smashing dust ups in arid desert landscapes to down and dirty races through rubbish-strewn city streets, FlatOut’s PSP debut is yet another gritty excursion into racing carnage.
