This is a great,large map.The water fall is prety cool,created of three conveyors(I din't see more then 3).The details are very goodI noticed some cameras and the lava was going up and down(there was also a waring sound about that).The crain holding a platform with some crates was a trap.I din't noticed any bugs.
OH!And I saw some screen-shots of the map made in the editor.
This is a very cool map,man.Contue making such gret maps.
P.S.Even Valve's maps aren't that good.
