Francis of Left 4 Dead 1 is very famous of his line "Merry Christmas" in the game trailer. Some of the game fans made this creative survivor vs zombie scene and I never expected a zombie so elite like that he has to face in this scene.
Anyway, I prefer the cast of L4D1. The recent version of it doesn't have cool characters as good as them. Zoey, Francis, Bill and Louis >Coach, Ellis, Rochelle and Nick.
