Unreal Tournament 2007: All About Vehicles (Part 1)

[PS3] Insider info on UT's war machines, direct from the developer

"The hoverboard allows you to tool around the map at three times the normal walking speed, so you can get into the fight quickly. For balance reasons we made it so you can't use any of your weapons on it and you're pretty vulnerable. If you take any amount of damage, you're going to get knocked off and it'll take you a second to get back on your feet - and that's usually all it takes to get you killed.
