We broke the limits multiple times, having too much geometry, too much dynamic stuff going on, too much animations, and so on. Some of our levels are so complex and detailed that optimizing them took entire months. You could see this as a joke, but it’s not. We are simply pushing the very limits of the Left 4 Dead engine to make room for all our ideas. A sequel to Left 4 Dead was released in the meantime and we’re doing our best to catch-up on two games at the same time. Unfortunately, this has taken way more time than we initially thought and that’s all water under the bridge now. We were sick of playing rubbish campaigns that overlook everything and didn’t even try to create any ambiance nor any sense of fear and desolation in this creepy universe. We played this game so much and always on the same campaigns that we believe it needs fresh new content, quickly.

We are playing Left 4 Dead together since the early days, during the Festival du Jeu-Vidéo in Paris, in 2008 (before the release). Be aware that this campaign is built the Valve way, we are not trying to revolutionize anything, we just want to provide more content to this awesome game. “I Hate Mountains” is the name of a brand new Left 4 Dead 1 & 2 campaign made by three French friends. No, it’s not a joke, and no, we don’t really hate mountains.
