Zombie Blitz 1940 is a real-life ride...experience...thing, where 14 people are ushered through tunnels beneath London's Waterloo station while dudes dressed like Nazi zombies try and eat their living flesh.
So, yes, it's Call of Duty's zombie mode. Only without the score counters, and shrieking 12 year-olds. Instead, you'll get shrieking grown-ups.
