survival_outpost_snow Alien Swarm
Author: Asus
This is a survival map
You have to hold out in an outpost for 10 minutes and then an airship comes to save you.
This is my first Alien Swarm map
I hope you like it.

How to install:
Extract the .vpk file to: C:\Program Files\Steam\steamapps\common\alien swarm\swarm\addons
Edit:
How to play custom maps:
type "map survival_outpost_snow" for a singleplayer server in the console and it should work
and for a multiplayer server type "changelevel survival_outpost_snow" in your console when your hosting a server.
And im currently working that the map shows up in the campaign section.
