Long Barrel mod for Half-Life 2

Long Barrel is the story of a secret "operator" that goes by the code-name Long Barrel, a nickname he earned during the Black Mesa incident for providing accurate sniper fire for the United States Marine Corps. Nowadays, however, Long Barrel keeps the name for the fact that his favorite weapon for operations is the .500 S&W Magnum. Another favorite weapon of Long Barrel's is his custom-made "Keyblade", a magnificent weapon provided to him by his former comrade, Colonel Bath, who is a very significant figure in this story. Long Barrel has been living in the outlands of City Twelve for the past six months now, doing low-life (what he calls it) jobs such as covering rebel convoys from the array of lifeforms that reside in the outlands. Today, however, is different. Major Tom, another long-term comrade of Long Barrel's (Long Barrel saved Major Tom's life from a houndeye.), has a very important mission for Long Barrel... Colonel Bath is said to be in City Twelve. Get him back to us.
