Follow the Liter, L4D1 Campaigns, Scavenge? Follow the Liter. Scavenge one can at a time. No more fighting over what cans to grab first. This Mutation spawns only one group of cans at a time, so survivors know exactly where to go. There is only one problem: the Infected know exactly where they are going. We dare you to give it a try. Most anticipated L4D1 Map? Dead Air and its hunter perches leap to the top with 40%, Blood Harvest’s corn fields plow into second place with 22%, Death Toll Church Guy rings in at 19%, Crash Course drove its van into last with 11% and 8% of you have no opinion on how much fun the rest of us are going to be having. Scavenge? Since this week's mutation is a play on Scavenge, we are curious. Are you going to play at least one round of Scavenge in the original Left 4 Dead campaigns once they are ported to Left 4 Dead 2?
