Members - Hangover mod for Half-Life 2

In this single player level for Half-Life 2, Gordon Freeman (the player) finds himself on the sea shore with a terrible hangover. He is surrounded by empty beer bottles a few Headcrab corpses and a bicycle. Does not remember anything about how he got there or what happened there and the night before. Sets off to find out and as usual gets into a bunch of “fun” activities along the way.
