The version of Hammer supplied in the Half-Life 2 SDK may work with these tutorials, but it has not been tested. The tutorials are all written around creating original Half-Life (Gold Source) maps and not Half-Life 2 maps. It is most likely possible to import Half-Life 2 maps into GoldenEye, but these guides are not geared to it."@en . .
