From the back of the box:
We'll make this quick. You're holding the new, super accelerated #1 world's leader in race games. It's jammed with twice the programming horsepower of the original Top Gear. So you can scream through 64 cities in 16 countries, twisting, turning, jumping, spinning and flipping at speeds over 200mph. Solo or head to head, day or night, rain or shine, fog or snow. Plus if you win enough prize money you can buy incredible engine, tyre, transmission, nitro system and armour upgrades and you've got new on screen power ups to keep you revved to the redline. So get your rear in gear because there's nothing half fast about it.
For 1 or 2 player simultaneous racing. 8 megs.
