"Andrew "Outatime" Wells has been in the mapping scene for some time now. He's has been working on a single map based off the Recoon City Police Department from Resident Evil 3 (Since back in 2006). When news of Left 4 Dead reached his ears, he scratched the single map idea and came up with a plan on creating a full campaign inspired by Resident Evil 3. Now, the campaign is in full swing and it looks amazing."
