Many vehicles (like weapons) you eventually get free by completing various tasks, but you may have to buy addon weapons separately. I generally don't use 'em, except rarely to drive pell mell across the maps

After playing TOB a couple more hours I've decided the combat model is too retro/primitive, and zombies don't cut it either. They stagger, they burn, they rush you in dribs and drabs... Ho hum.

Will nuke and try on TNO next.

Seriously disappointed in TOB zombies. Nazi zombies ought to be the most vicious, cunning, relentlessly in-your-face zombies in all of video gaming. TOB zombies are pathetic, shambolic dead meat puppets that scamper up and slap you with a stinking paw before you blow their fucking heads off.  LMAO
