I have an original cd which includes everything from AI to multiplayer to other created games like tug of war, survivor, meron din akong sotis and more.
pero kung hindi orig and you only downloaded a scII copy I suggest wag mong kunin yung sa mismong blizzard at wala kang mapapala dun, maraming mga torrents na may included na AI mag hanap ka lang sir sa google dami dun.
