David Blume to Joyce Mayorga, David BlumeYou must have seen this. Best Easter Egg ever.
This is one of the most detailed and amazing easter eggs I've ever found in a campaign EVER. Anyone who has Left 4 Dead 2 on PC needs to download this and play it ASAP. If you do, it needs to be played on a local server due to some official dedicated servers being retarded. Will be patched soon, though. Link to the map: http://www.l4dmaps.com/details.php?file=9754
