14 Popular Games Where You Were Overrun By Hordes of Zombies

KILLING FLOOR 

2009’s Killing Floor is a much better game than people give it credit for. It may not have done anything ground breaking, but it was loads of fun. In one of its two modes, players had to fight against waves upon waves of zombies, much like Call of Duty’s zombies mode, and these waves got progressively stronger. Fighting of against these hordes of zombies was great, adrenaline fuelled fun that we won’t soon forget, and hopefully the upcoming sequel will pull it off just as well as the first game did.
