Half-Life: Urban Conflict mod

BACKSTORY: The date is May 18, 200-. The alien invasion has spreaded into the globe, the governments are under attack, their military aren't capable of handling such disaster. You are from Valkrestenstein, a norther European country under dictatorship. The martial law is in effect, there is a code black emergency protocol across the country, the citizens evacuated into the main cities bunkers; the rest of citizens found on the street are killed on sight. Your rescue helicopter, attacked by an alien aircraft, has crashed inside the skyscraper that you were supposed to evacuate. Standing on the rooftop, you decide to escape on your own. THE MOD ITSELF: Hello everyone! This mod is called "Urban Conflict" a mod that is heavly inspired by the Early Half-Life 2 architecture, art style and maps. This could be the "1999 version Half-Life 2 in GoldSRC" but I want to take some liberties regarding the story and the map layout.
