A classic zombie-themed cooperative FPS that is a staple to the free-to-play section on Steam. Although there isn't as many people as there used to be playing this game, you'll always find servers with people. I recommend giving this one a try, especially to those who are newer to the PC landscape and have no money for games yet, or if you're just dirt broke.
