PlanetSide 2 lore to find out, and luckily the official website is here to help.
Today's reveal showcases the Quad, and Sony Online Entertainment tells us that "it has the highest top speed of any ground vehicle and is easy to acquire." As you would expect, the speed comes at a price, and let's just say that you don't want to be riding on a Quad when it takes a hit. Head to the PS2 website for a couple of screenshots and some backstory.
When you're done reading about the Quad, click on over to SOE's Liberator reveal to get the goods on another Nanite Systems product. The Liberator is a gunship, and while it boasts a ton of firepower and decent armor protection, it pays for its bristling bulk by being quite slow in the air.
