Counter-Strike conversion of the popular "DoD_Green_AFK_Final" map for "Day of Defeat".
The bomb can be planted on the top floor of the middle of the overpass.
Note that there is an overview map included in the ZIP, and also included is a carefully created navigation mesh file for the CSCZBots/WeedsBots/ZBots (complete with radio "place names").
Snag it from here if you're so inclined (screenshots located there):
