This is Gold Edition of ALFA: Antiterror - Advanced War Tactics, it includes updated and fixed version of both original game and expansion pack, plus some additional content. Gold Edition was released only in Russia and has only Russian language version, there was no foreign release of this edition.
It is recommended to play with mod Needful Things, since the original game was too hard, that mod fixes the balance, also it adds new weapons and equipment. You can find more mods in Russian fan community

Thanks a lot! File is ok now.
@DEE_DECKARD Updated that archive, it was broken indeed. Now it should work okay, please check it
The "Collection of mods (Needful Things included)" zip file is corrupted. Downloaded it twice to be sure. Tested with latest WinRar, 7-zip and WinZip.
No comment nor review for this game at the moment.
