California custom truck builder Rezvani's latest creation takes the Escalade and transforms it into a futuristic military vehicle that almost looks like the "Warthog" truck from the video game Halo. 

"The goal was to put a science fiction video game concept car in people's driveways," Rezvani CEO Ferris Rezvani told Fox News. 

The personal security vehicle starts at $249,000, but once you add the military package (armor plating), night vision systems, rifle compartment, tire inflation and deflation kit, and massive supercharged V8 engine -- the cost is bumped up to a half million dollars.
