Your mission was to find and destroy a secret alien lab. Now you have crash landed and are stranded in an infested forest. Find your way to the underground entrance and complete your mission.
Be sure you read any hints on the screen and pay attention to the areas around you. Check computers, look for keys, and conserve your gear, you're going to need it.

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
