The OutPost v4 (nominated in 2009 for Best Series, Best Surprise Ending and Best New Surface) has us taking back the camp and revealing the "prize" that we have been defending. (Please play v2 and v3 first.) After v3 and the glacial flood, well you guessed it, things froze over, yes we have ICE. This mission is pure stealth so be patient and let the guidance tell you what to do. In the end there is a tribute to the original "game play" movie (War Games). By the way, it will take a minimum of 1 hour to play through. Enjoy.
