[STORY]
Old soviet helicopters are the only thing that can deploy troops on short notice and lead attacks on Combine outposts. There are only a dozen of them that are functioning, these are essential to the rebellion and having one of them taken away is a huge loss. Well that very thing just happened today, one of our helicopters has been taken straight from it’s hangar. It has been tracked down to some abandoned village one the outskirts of City 13. You must retrieve it at all costs, Good luck.
