full map of Surface Tension if it didn't so horribly overlap. i also didn't check, but i'm pretty certain that Questionable Ethics, Forget About Freeman, Foxtrot Uniform and The Package could all fit into this map with minimal editing.
in Half-Life 2's fourth chapter; Water Hazard, in the maps canals_10 and canals_13, a town can be seen on a hill in the distance. the game heavily implies that this town is Ravenholm, but it cannot be it as the tunnel to it goes in the opposite direction.
