Return - Episode 1 is a new Gordon´s adventure.Survive the disaster and fight your way to the surface...
small Gordon´s adventure - play in night - some lvls are too dark - first two lvls in custom game - next maps start with console - use readme file
if you like the zombie sounds - they are from HL : Survive in catacombs
The maps are cool but why aren't they connected? It really takes you out of the game when you stumble upon a dead end and text tells you to "type map x"
