World War II was horrific enough. But add a healthy dose of the undead, and you've got a real problem. Set during WWII in the tunnels below London's Waterloo Station, Zombie Blitz 1940 pits you and your group of Allied companions against an oncoming Nazi zombie army. With vintage costumes, authentic military equipment, and confined, nearly pitch-black spaces, it's as close as you can come to reliving the horror that thankfully never was.
