Vigilante 8 is good, but 2nd Offense is all that and much more than a bag of potato chips.  Some of the new additions include the ability to score new chassis for your cars and wheel attachments that turn your car into a motorboat, a UFO, or a snowmobile.  All the characters from the original are back (except 3), although they drive different cars and in most cases have different special weapons.  Even Y the alien makes an appearance, this time disguised as a mysterious garbage man scavenging for parts to repair his damaged Luxo Saucer.  Some of the new characters include a monkey disguised as an astronaut, a religious fanatic, a ninja, and a robotic cowboy.  Every level is interactive to the core and you can rocket into space, cause nuclear explosions, compete in downhill sports and unleash a giant radioactive ant that goes on a rampage through Arizona.
