The survivors took a wrong turn on the way to the airport...

A Left 4 Dead adaptation of the Half-Life 2: Deathmatch map "dm_runoff"

A "quick" project I wanted to pick up just to test myself. It ended up taking more than a full time work week to make this happen. I'm pretty happy with the results, all things considered.

This map has: - Custom assets, including textures and models from Half-Life 2 and Counter-Strike: Source, homemade graffiti, and a few fake ammo models just to mess with you. - An implementation of Brain Dead's wonderful L4D1 Charger, Jockey, and Spitter. - Tweaked geometry from the original, such as the cut sewer tunnel connecting the docks and drains. - All the L4D functionality needed to play the game!

Known Bugs & Notes: - There are two seams in the world geometry at the entrance to the drains. These have been very stubborn, I'm sure I'll fix them eventually. - Sometimes, the Spitter's acid effect that drips from her mouth doesn't load. It seems to work most of the time, though. - Survivor bots really like to break their legs trying to make the bridge jump at the docks. Tanks sometimes like to spawn slightly inside walls and then die. The navmesh is not perfect and I'm still chipping at it. - I did not really get the opportunity to playtest Versus Survival, so there may be issues. - The Nightmare mutation is very, very orange. - There's a number of fun references in the graffiti. Try and find them all!
