GameSpot reviews Twisted Metal: Head On

Twisted Metal: Head-On for the PSP was considered to be the sequel to Twisted Metal 2 that had never been, and one of the best gaming options available at the portable system's launch. Forget about that other Twisted Metal 3; Head On expanded upon some ideas from the original games, refined a few others, and blew the dust from some fun that had been missing from the series for quite a while. So, the question is: What does Twisted Metal Head On: Extra Twisted Edition bring to the PlayStation 2 other than a port of a two-year-old game built for lesser hardware?
