it's been a while but I finished something half life related again. Basically it's a map that I have build in 2011 for AG of which I thought that I have lost the map files but just stumbled across a few ago.
Original mapname was "The_Tube" refering to the large tube in the middle of the map. I have greatly overhauled the visuals and opened up several places for better gameplay and on recent testing it worked very well in AG and will also work in HLDM, especially in teamplay. Every room & every part of the map has been worked on.
Attached are some screens and a link to gamebanana. I have also attached the old version for curiousity.
