St. Olga

"You must be here to take on the Combine. Not sure what one man can do, but... no other reason to visit St. Olga at a time like this."

- The Fisherman

St. Olga was a relatively large coastal village that was planned to be a part of Half-Life 2 but was dropped during the game's development. St. Olga was restored, however, in Half-Life 2: Lost Coast.

Role
St. Olga was planned to be a Byzantine monastery with a single inhabitant, a middle-aged and mentally unstable (though not violently so) fisherman. It was meant to be in between Highway 17 and Sandtraps. It was cut from Half-Life 2 but was brought back for Lost Coast.

Lost Coast
In Half-Life 2: Lost Coast, Gordon Freeman awakens in a shallow tide on a beach near St. Olga. The Fisherman has been waiting for him, and tells him that he must be there to "take on the Combine" and take out their headcrab-launching gun, which is attacking the village. The monastery near St. Olga had been turned into a Combine staging area for the launching of headcrab shells which players were able to see operate in real-time. As the game progresses a few headcrab shells target St. Olga and when some of them hit the town, they cause fires. Even against a Hunter-Chopper, a member of the Overwatch Elite, and squads of Overwatch troops, Freeman triumphed against the Combine and sabotaged their shell machine. The Fisherman intended to take him to St. Olga (who had apparently fought off the headcrabs) for a feast of leeches, but Freeman supposedly had much more important things to do other than eat leaches.

Trivia

 * The town may be named after St. Olga, the first Christian queen of Kiev, Russia, and the patron saint of widows.
