That looks amazing, consider me teased! I love L4D too, and also can't wait for 3, but its fun to see innovation in this genre. The complaint I have after logging hundreds of hours into left 4 dead is mainly a matter of the game engine they had in 2010 - it just needs a refresh to keep pace with our beefier graphics cards and such. Plus, I hope they can vary the zombies more - by that I mean the skins; they need a random generator so no two zombies look alike. In this coming game, Dying Light, the scenery, the world, and the zombs look spectacular!
