If you play Left 4 Dead or Left 4 Dead 2 on the PC, you probably know there's a pretty robust L4D modding community. The mods can be pretty hit or miss, depending on how invested the modders are, but I, myself, am loath to pass up a perfectly good opportunity to shoot, decapitate, and otherwise maim zombies in new environments for simply the price of my time spent downloading the mod. A highly-anticipated (it's been in the works for a long, long time) Left 4 Dead fan-made campaign has recently been released, entitled "I Hate Mountains." It sports five new maps containing a mansion, lakefront, lumberyard, and uh, we're assuming mountains through which Francis and company must trek.
